Question

Hema bought two pairs of Jazz for 1450 each she sold one of them at gain 8% and other loss of 4% find the gain or loss percent in the whole transaction ​

Answer 1

Given:-

• Hema bought two pair of jeans for ₹1450 each. She sold one of them at a gain of 8% and the other at a loss of 4% .

To find:-

• Find her gain or loss per cent in the whole transaction

Solutions:-

• CP of the first jeans = Rs 1450

• Profile % on the first jeans = 8 %

Profile = 8 % of Rs 1450

= 8/100 × 1450

= 8/10 × 145

= 4/5 × 145

= 4 × 29

= Rs 116

SP of the first jeans = Rs 1450 + Rs 116

= Rs 1566

CP of the second jeans = Rs 1450

Loss = 4 % of CP

= 4/100 × 1450

= 4/10 × 145

= 4/2 × 29

= 2 × 29

= Rs 58

SP of the second jeans = Rs 1450 - Rs 58 = Rs 1392

Total CP of two jeans = CP of first jeans + CP of second jeans

= Rs 1450 + Rs 1450

= Rs 2900

Total SP of two jeans = SP of first jeans + SP of second jeans

= Rs 1566 + Rs 1392

= Rs 2958

Thus,

Total SP of two jeans > Total CP of two jeans

Gain = Total SP of two jeans - Total CP of two jeans

= Rs 2958 - Rs 2900

= Rs 58

Gain % in the whole transaction

= gain/Total CP of two jeans × 100%

= 58/2900 × 100

= 58/29

= 2 %

Hence, gain or loss per cent in the whole transaction is 2%.
