A fruit-seller bought 75 kg apples at Rs. 30 per kg. He sold one-third apples at a loss of 5%. At what rate should he sell the remaining so that his overall gain is 10%?

Step-by-step explanation:

Total cost:

One-third sold at a loss of 5%:

Amount needed to get 10% gain:

Rate required:

A fruit-seller bought 75 kg apples at Rs. 30 per kg.

Total cost = 75×30

= 2250

He sold one-third apples at a loss of 5%.

one-third sold at a loss of 5%

= 1/3 × 75 × 30 × (1 - 0.05)

= 712.5

Amount to get 10% gain

= 2250 × (1 + 0.1) - 712.5

= 1762.5

The rate that the shopkeeper should sell :-

= 1762.5 ÷ 2/3 (75)

= 1762.5/50

= Rs. 35.25

the correct answer option is d. la = πrs.

step-by-step explanation:

we know that for a right cone, the lateral surface area is given by:

lateral area of right cone =

here the value under the square root is equal to slant height so replacing this value by in the formula to get:

lateral area of right cone =

therefore, the correct answer option is d.
