Answer:
An old woman buys 25 berries for rupees 10. How many berries should she sell for rupees 10 such that she gains 25%
CP for 25 berries = Rs 10
CP for 1 berry = 10/25 = 0.4 Rs
She needs profit of 25%
P% = P/CP × 100
P = 0.1
SP = CP + P = 0.5 Rs
Now she needs to sell 10/0.5 = 20 berries for 10Rs to get 25% profit
