1.	An earphone Rs. 750 is offered at 8% discount and a headphone Rs. 1,250 at 20% discount. If Chinmay buys 5 earphones and 3 headphones, what is the effective discount he gets (in %)?1. 122. 143. 154. 16
Answer» Correct Answer - Option 2 : 14 Given: Marked price of earphone (MP_e) = Rs. 750 Marked price of headphone (MP_h) = Rs. 1250 Formula used: S.P = M.P × (100 – D%)/100 Where D% → Discount% S.P. → Selling price M.P. → Marked price Calculations: S.P of an earphone = 750 × (100 – 8)/100 ⇒ 750 × 23/25 = Rs. 690 S.P of a headphone = 1250 × (100 – 20)/100 = 1000 Total S.P. of 5 earphones and 3 headphones = 5 × 690 + 3 × 1000 = Rs. 6450 Total M.P. of 5 earphones and 3 headphones = 750 × 5 + 1250 × 3 = 7500 Discount = Rs. (7500 – 6450) = Rs. 1050 Discount% = (1050/7500) × 100 = 14% ∴ The required discount% is 14%

Answer» Correct Answer - Option 2 : 14

Given:

Marked price of earphone (MP_e) = Rs. 750

Marked price of headphone (MP_h) = Rs. 1250

Formula used:

S.P = M.P × (100 – D%)/100

Where

D% → Discount%

S.P. → Selling price

M.P. → Marked price

Calculations:

S.P of an earphone = 750 × (100 – 8)/100

⇒ 750 × 23/25 = Rs. 690

S.P of a headphone = 1250 × (100 – 20)/100 = 1000

Total S.P. of 5 earphones and 3 headphones = 5 × 690 + 3 × 1000 = Rs. 6450

Total M.P. of 5 earphones and 3 headphones = 750 × 5 + 1250 × 3 = 7500

Discount = Rs. (7500 – 6450) = Rs. 1050

Discount% = (1050/7500) × 100 = 14%

∴ The required discount% is 14%
