Hey Mate

Question:

Sarita bought eggs at 8.40 a dozen .At what price per hundred must she tell them so as to earn a profit of 15%

Answer:

cost of 1 egg will be 8.40/12=0.70
so 15% profit on 1 egg is
0.70*115/100=0.805

Answer 2

Answer:

→ SP = ₹ 80.5 .

Step-by-step explanation:

→ Cost of a dozen eggs = 8.40 .

→ Cost of 1 egg = 8.40/12.

[ Since , 1 dozen = 12units ] .

= ₹ 0.7 .

 

→ Cost of 100 eggs = 0.7 × 100 => rs 70

Given :-

→ CP = rs 70

→ Gain % = 15%

Solution :-

∵ SP = ( 100 + gain% )/100 × cp

⇒ SP = (100+15)/100 × 70

⇒ SP = 115/100 × 70

⇒ SP = 115×7/10

⇒ SP = ₹ 805/10

∴ SP = ₹ 80.5

Hence, it is solved .
