Question

mama 3 oranges for Rs 4 and sells 4 oranges for Rs 100 and his gain or loss percent

Answer 1

Cost price of 3 oranges = rs. 4
C.p. of 1 orange = rs. 4/3 = rs 1.33

Selling price of 4 oranges = rs. 100
S.p. of 1 orange = rs. 100/4 = rs. 25.00

Profit = S.p. - C.p.
Profit = 25.00 - 1.33
profit = rs. 23.67

Profit% = profit ×100/Cp.
= 23.67×100/1.33
=1779.7%
