Answer 2

Pooja has enough money to buy 35 oranges at the rate of Rs 5.40 per orange .

∴ Total money with her = number of oranges × rate per orange

⇒ Total money with her = Rs 5.40 × 35

⇒ Total money with her = Rs 189 .

Now the price of each orange decreases by 90 paise .

100 paise = 1 Rs

90 paise = 0.9 Rs

New price = Rs 5.40 - Rs 0.9 = Rs 4.50

New number of oranges = Total price with her / new price rate

⇒ No of oranges = Rs 189 / Rs 4.50

⇒ No of oranges = 42

∴ Number of oranges = 42 .
