Question

Abdul sold 2 toy cars for R.S 29.90 each. On one, he gained 10% but on the other he lost 10%. Find his total gain or loss percent.

Answer 1

Answer:

0.99%

Step-by-step explanation:

1st Toy Car:-

S. P of the car = Rs 29.90

Gain = 10%

[ If S.P = 100+ Gain 10 % = 110]

[ Then C.P = 100 ]

therefore C. P = 29.90×100/110 = Rs 27.18.

2nd Toy Car:-

S.P of the car = Rs 29.90

Loss = 10%

[ If S. P = 100- loss 10% = 90]

[ Then C.P = 100]

therefore C. P = 29.90×100/90 = Rs 33.22

Therefore:-

Total C. P = Rs 27.18+ Rs 33.22 = Rs 60.4

Total S. P = Rs 29.90 ×2 = Rs 59.8

Therefore, loss = Rs 60.4- Ra 59.8 = Rs 0.6

therefore, loss percent (%) = 0.6/60.4×100 = 0.99%
