Question

17. A computer set was sold at a profit of 7%. If it had been sold at a profit of 10%, the profit could have
been 780 more. What is its CP?
explain​

Answer 1

Answer:

Let the cost price of the computer set be Rs 100x. So, SP = Rs 107x.

Now, 110x - 107x = 780

=> 3x = 780

=> x = 260

Hence, CP = 100 * 260 = Rs 26000
