NEUROLOGY

CANCER CENTER

Total no. of nurses in the hospital = 100

Number of Nurses who do not know Hindi = 8 + 4 + 8 + 9 + 3 + 12 =44

Required percentage = 44/100 × 100 = 44%

In cancer center, employees who know Tamil is approximately what percentage of employees in cancer center who do not know Tamil?

Total employees = 200

NEUROLOGY

CANCER CENTER

In cancer center,

Employees who know Tamil = 2 + 3 + 5 + 9 + 12 + 12 + 4 + 6 = 53

Employees who do not know Tamil = 10 + 9 + 8 + 9 + 9 + 12 = 57

∴Required percentage = 53/57 × 100 = 92.98% ≈ 93%

Out of the employees in cancer center, what is the ratio of the number of doctors knowing English to the number of nurses knowing Hindi?

Total employees = 200

NEUROLOGY

CANCER CENTER

In cancer center,

Number of doctors knowing English = 10 + 9 + 12 + 4 = 35

Number of nurses knowing Hindi = 9 + 12 + 9 + 6 = 36

Thus, the required ratio is 35: 36

What is the loss/gain percentage of Nike?

Let the cost price of Nike shoe be INR x

Marked up price of Nike shoe is 200% of the cost price

⇒M.P. = 200% of x

⇒M.P. = INR 2x

Discount given is 45% on the marked price

As we know, Selling price = M.P. – discount

⇒S.P. = 2x – 45% of 2x

⇒S.P. = 2x – 9x/10

⇒S.P. = INR 11x/10

Now, Gain = S.P. – C.P.

⇒Gain = 11x/10 – x (∵S.P. > C.P.)

⇒Gain = INR x/10

Gain % = ((x/10)x100=10%

Thus, there is a gain of 10% on Nike shoe

If the cost price of the Puma shoe and Adidas shoe is equal then the selling price of Puma shoe is how much % more than the selling price of Adidas shoe.

Let the cost price of Puma be INR x

Marked up price of Puma is 150% with respect to C.P. of Puma shoe

⇒M.P = 150% of x

⇒M.P. = INR 3x/2

Discount given is 25% on the marked price

As we know, Selling price = M.P. – discount

⇒S.P. = 3x/2 – 25% of 3x/2

⇒S.P. of Puma shoe = INR 9x/8 = INR 1.125x

According to given information:

The cost price of Adidas is also INR x

Marked up price of Adidas is 160% with respect to C.P. of Adidas shoe

⇒M.P = 160% of x

⇒M.P. = INR 8x/5

Discount given is 50% on the marked price

As we know, Selling price = M.P. – discount

⇒S.P. = 8x/5 – 50% of 8x/5

⇒S.P. = 4x/5

⇒S.P. of Adidas shoe =INR 0.8x

Profit=.325x

∴Required percentage = 0.325*100/.0.8= 40.625

If the cost price of Reebok is increased by 10% and other percentages (marked price /discount) remain same, then how much more percent loss company will get as compared to previous loss?

Let the previous C.P of Reebok shoe be INR 100

Marked up price of Reebok is 180% with respect to C.P. of Reebok shoe

⇒M.P = 180% of 100

⇒M.P. = INR 180

Discount given is 60% on the marked price

As we know, Selling price = M.P. – discount

⇒S.P. = 180 – 60% of 180

⇒S.P. = 180 – 108

⇒S.P. of Reebok shoe = INR 72

∴Loss = 100 – 72 = INR 28

Now, loss percentage = 28/100 × 100 = 28%

According to the given information:

If C.P. of Reebok shoe increase by 10%

Then, New C.P. = INR 110

Marked up price of Reebok is 180% with respect to C.P. of Reebok shoe

⇒M.P = 180% of 110

⇒New M.P. = INR 198

Discount given is 60% on the marked price

As we know, Selling price = M.P. – discount

⇒S.P. = 198 – 60% of 198

⇒ S.P. = 198 – 118.8

⇒ New S.P. of Reebok shoe = INR 79.2

∴ Loss = 110 – 79.2 = INR 30.8

Now, loss percentage = 30.8/110 × 100 = 28%

Thus, there is no increase in loss.

Which shoe company makes the highest profit, if the C.P. is INR 500 of each shoe?

C.P. of Puma shoe = INR 500

Marked up price of Puma shoe is 150% of the cost price

⇒M.P. = INR 750

Discount given is 25% on the marked price

⇒S.P. = 750 – 25% of 750

⇒S.P. = 750 – 187.5

⇒S.P. = INR 562.5

⇒Gain on Puma shoe = INR 62.5

C.P. of Nike shoe = INR 500

Marked up price of Nike shoe is 200% of the cost price

⇒M.P. = INR 1000

Discount given is 45% on the marked price

⇒S.P. = 1000 – 45% of 1000

⇒S.P. = 1000 – 450

⇒S.P. = INR 550

⇒Gain on Nike shoe = INR 50

C.P. of Adidas shoe = INR 500

Marked up price of Adidas shoe is 160% of the cost price

⇒M.P. = INR 800

Discount given is 50% on the marked price

⇒S.P. = 800 – 50% of 800

⇒S.P. = 800 – 400

⇒S.P. = INR 400

⇒Loss on Adidas shoe = INR 100

C.P. of Reebok shoe = INR 500

Marked up price of Reebok shoe is 180% of the cost price

⇒M.P. = INR 900

Discount given is 60% on the marked price

⇒ S.P. = 900 – 60% of 900

⇒ S.P. = 900 – 540

⇒S.P. = INR 360

⇒Loss on Reebok shoe = INR 140

C.P. of Bata shoe = INR 500

Marked up price of Bata shoe is 125% of the cost price

⇒M.P. = INR 625

Discount given is 10% on the marked price

⇒S.P. = 625 – 10% of 625

⇒S.P. = 625 – 62.5

⇒S.P. = INR 562.5

Now, Gain = 562.5 – 500

⇒ Gain on Bata shoe = INR 62.5

Hence, Bata and Puma made the highest gain.

If the profit of Nike and Bata shoe is same and C.P. of Bata is INR 400 then find the C.P of Nike shoe?

The cost price of Bata shoe be INR 400

Marked up price of Bata shoe is 125% of the cost price

⇒M.P. = 125% of 400

⇒M.P. = INR 500

Discount given is 10% on the marked price

As we know, Selling price = M.P. – discount

⇒S.P. = 500 – 10% of 500

⇒S.P. = 500 – 50

⇒S.P. = INR 450

Now, Gain = S.P. – C.P.

⇒Gain = 450 – 400 (∵ S.P. > C.P.)

⇒Gain = INR 50

According to the given information

Gain on Nike shoes is INR 50

Let the cost price of Nike shoe be INR x

Marked up price of Nike shoe is 200% of the cost price

⇒M.P. = INR 2x

Discount given is 45% on the marked price

⇒S.P. = 2x – 45% of 2x

⇒S.P. = 2x – 9x/10

⇒S.P. = INR 11x/10

∴ Gain = 11x/10 – x

⇒ Gain = INR x/10 = 50

⇒ x = 500

Hence, C.P. of Nike shoe is INR 500
