a) 50, b) 60, c) 70, d) 80​

Answer 1

Answer:

60 is the correct answer

Answer 2

Answer: option d) 80

Step-by-step explanation:

Step 1:

S.P. of 64 apples = Rs. 60

Gain% = 25%

∴ C.P. of 64 apples

= $\frac{100}{100+G}*S.P.$

= $\frac{100}{100+25}*60$

= $\frac{100}{125}*60$

= Rs. 48

Step 2:

Loss% = 40%

We have to find the selling price of 64 apples so that a loss of 40% occurs in the final transaction.

∴ S.P. of 64 apples

=$\frac{100-L}{100}*C.P.$

= $\frac{100-40}{100}*48$

= $\frac{60}{100}*48$

= Rs. 28.8

Now,

No. of apples sold in Rs. 28.8 = 64

∴ No. of apples sold in Rs. 36 = (64/28.8) * 36 = 80

Thus, he should sell 80 apples for Rs. 36 to make a loss of 40% in the transaction.
