by

A wholesaler buys a computer from a manufacturer for ₹ 40000. He marks the price of the computer 20% above his cost price and sells it to a retailer at a discount of 10% on the marked price. The retailer sells the computer to a consumer at the marked price. If the rate of sales tax (under VAT) is 10% at every stage, then choose the correct answer from the given four options.

The marked price of the computer is
(a) ₹ 40000
(b) ₹ 48000
(c) ₹ 50000
(d) none of these

Solution:

(b) ₹ 48000

Explanation:

C.R of computer for manufacturer = ₹ 40000
After marking 20% above the C.R, the price
= ₹ 40000 x \\ \frac { 100+20 }{ 100 }
= ₹ 40000 x \\ \frac { 120 }{ 100 }
= ₹ 48000

Cost of the computer to the retailer (excluding tax) is
(a) ₹ 36000
(b) ₹ 40000
(c) ₹ 43200
(d) ₹ 47520

Solution:

(c) ₹ 43200

Explanation:

Rate of discount = 10%
∴ Sales price after discount
= ₹ 48000 x \\ \frac { 100-10 }{ 100 }
= ₹ 48000 x \\ \frac { 90 }{ 100 }
= ₹ 43200
