A man had a certain amount with him. He spent 20% of that to buy an article and 5% of the remaining on transport. Then he gifted Rs 120 and left with Rs 1400. The amount he spent on transport is:

80

Let total amount = Rs.100

Spend on article = 20% of 100 = 20

Remaining amount = 100 - 20 = 80

Amount spend on transport = 5% of 80 = Rs.4

Remaining amount = 76

ATQ,

⇒ 76R - 120 (gift) = 1400

⇒ 76R = 1520

⇒ 1R = 20

So, amount spend on transport = 4R = 4 × 20 = Rs. 80
