Answer 2

Answer:SP of 45 lemons = ₹40 SP of 1 lemon = ₹40/45=8/9

Loss = 20%

CP = SP ×100/(100 - loss%) = 8×100/9(100 - 20) = 8×100/9×80 = 10/9

SP = CP + 20%of CP = 10/9 + 20/100×10/9 = 10/9 + 2/9 = 12/9

No. of lemons he should sell in ₹24 to gain 20% = 24÷9/12 = 24×9/12 = 18

; 18 lemons he should sell for ₹24 to gain 20%
