Question

Prem sold a transistor to Sudhir at a gain of 10% and Sudhir sold it to Hari at a gain of 15%. Prem had
bought it for 500, what did it cost to Hari ?​

Answer 1

CP of Prem = 500

Now, if we sold to sudhir at 10% gain,

CP of Sudhir = 110% of 500 = 110×500/100 = 550

Now, sudhir sold it to hari at 15% gain,

CP of hari = 115% of 550 = $\frac{115}{100} \times550$ = 632.5

Therefore,

• Cost of hari will be ₹632.5
