Question

. A washing machine was bought for Rs.13760 & sold at a gain of 12 1/2
%. How
much did the seller receive?​

Answer 1

Answer:

C.P=13760

Gain=25/2%

S.P=13760×(100+100×25/2)/100

=13760×1350÷100

=1376×135

=185,760

Answer 2

Answer:

₹15480

Step-by-step explanation:

1st method

SP = 100+12½= 112½= 225/2

If CP is ₹100, then SP = ₹225/2

If CP is ₹1, then SP = ₹225/2 × 1/100

If CP is ₹ 13760, then SP= 225/2 × 1/100 × ₹13760/1 = ₹15480

2nd method

SP = (100 + gain%/100) × CP

= ₹(100+12½/100) × 13760

= ₹(100+25/2/100) × 13760

= ₹ (225/2×100) × 13760

= ₹ 15480
