| Q | 900 | 15 |
| R | 1020 | 30 |
| S | 1200 | 25 |
| T | 590 | 10 |
If product Q is sold at 53% profit and product S is sold at 80% profit, then what will be the sum of the cost prices of Q and S?
Show answer & explanation
Correct answer: C
Explanation
the correct answer is option 4 i.e 1000
MRP of product Q = 900
The selling price of product Q= 900 of (100-15)%
= 900 of 85%
= 900 × 85/100
= 765
If product Q is sold at 53% profit
Cost price of product Q = 765/(100 + 53) × 100
= 765/153 × 100
= 500
MRP of product S = 1200
The selling price of product S = 1200 of (100 - 25)%
= 1200 of 75%
= 1200 × 75/100
= 900
if product S is sold at 80% profit.
Cost price of product S = 900/(100 + 80) × 100
= 900/180 × 100
= 500
Sum of the cost prices of Q and S = 500 + 500
= 1000
