Question

Sarika bought bananas at 5 for rs. 7.50 and sold them at Rs. 20 per dozen. Find her gain or loss percent.
​

Answer 1

1. Step-by-step explanation:

Cp of 5 bananas = Rs. 7.50

so, Cp of per banana = Rs. 7.50 ÷5 = Rs. 1.5

Now,

Sp of 12 bananas = Rs. 20

so, Sp of per banana = Rs. 20÷ 12 = Rs. 1.67

Sp > Cp

hence, profit.

so,

profit (p) = Sp - Cp

= 1.67- 1.5

= 0.17

and

profit (gain) percent = (0.17×100) ÷ 1.5

= 11.33%

ans.

Answer 2

Answer:

Sarika bought 5 bananas = 7.50 rs

= 1 Banana is 7.50 / 5 = 1.50 rs

She sold them at 1 dozen = 20 rs

so 1 Banana sold at per rate = 20 / 12 = 1.666 rs.

= 1 Banana is 1.67 rs

So , she sold them 1.67 × 5 = 8.333

= now, we will have = 8.33 - 7.50

= 0.83 × 100 / 7.50

{ SP - CP / CP × 100 }

= 11.106 or 11.11% Ans.✍️
