${ \huge \fbox \pink {A}\fbox \blue {n} \fbox \purple {s} \fbox \green{w} \fbox \red {e} \fbox \orange {r}}$

3 eggs for 2 Rs. 1 egg = 2/3 Re. 1 egg = 3/5 Rs. Gain % = Gain/C.P * 100 = 1/30/(7/6) * 100 = 1*6/7*30 *100 = 100/7*5 = 20/7 = 2(6/7)% gain.

Answer 2

Answer:

Let us assume he bought 6 eggs -------- LCM of 2 and 3

CP of 6 eggs @ 2 for Rs 1 = Rs 3

CP of 6 eggs @ 3 for Rs 2 = Rs 4

Total CP = 3 + 4 = Rs 7

Total eggs = 6 + 6 = 12

SP of 12 eggs @ 5 per Rs 3

= 3/5 × 12 = 36/5 = 7.20 Rs

Profit = 7.20 – 7

= 0.20 Rs

Profit % = 0.2×100/7 = 2 6/7 %

Hope this is helpful for you.
