Question

Pooja has enough money to buy 36 oranges at their rate of rupees 4.50 per orange . How many oranges she can buy if the price of each orange is increased by 90 paise.

Answer 1

Cost of 1 orange = Rs 4.50
Number of oranges bought = 36
Cost of 36 oranges = Rs(36 × 4.50) = Rs 162

Now, increased cost of 1 orange
= Rs 4.50 + Re 0.90
= Rs 5.40

Number of oranges bought for Rs 162
= 162 / 5.40 = 30
