A man bought a shirt for ₹1000 and a pair of trousers for ₹2000. The discount offered on the shirt and the trousers were 20% and 50% respectively. What was the overall discount offered?

40%

Cost price of the shirt = 1000

Discount = 20% = 20% of 1000 = 200

Cost price of the trousers = 2000

Discount offered = 50% = 50% of 2000 = 1000

Total discount = 1000 + 200 = 1200

Total CP = 1000 + 2000 = 3000

Discount% = 1200 × \(\frac{100}{3000}\) = 40%
