- #3-ihis gain as percent; (ii) the number of articles sold to make a profit of Rs.75. (ii) the number of articles sold to make a profit of Rs.75.Ans : Gain = S.P. - C.P.
= Rs. 540 - Rs 450
= Rs. 90
∴ Gain = Gain/C.P. × 100
= 90/450 × 100
= 100/5
= 20% (ii) To make a profit of Rs. 90, the number of articles needed to be sold = 60
To make a profit of Re. 1 the number of articles needed to be sold = 60/90
To make a profit of Rs. 75, the number of articles needed to be sold = 60/90 × 75
= 4500/90
= 50 (ii) To make a profit of Rs. 90, the number of articles needed to be sold = 60
To make a profit of Re. 1 the number of articles needed to be sold = 60/90
To make a profit of Rs. 75, the number of articles needed to be sold = 60/90 × 75
= 4500/90
= 50
