I hope it helps you.

Answer 2

Solutions :-

Cost Price of 1 Dozen eggs = Rs 8.40 ( 1 Dozen = 12 units)
Cost Price of 1 egg = Rs (8.40/12) = Rs 0.7
Cost Price of 100 eggs = Rs (0.7 × 100) = Rs 70

Profit = 15%

Find the Selling price of 100 eggs to earn a profit of 15% :-

S.P = C.P + Profit% of C.P
= 70 + 15% of 70
= 70 + 0.15 × 70
= 70 + 10.50
= 80.50

Hence,
Selling price of 100 eggs to earn a profit of 15 % is Rs 80.50
