| Anita had to do a multiplication. Instead of taking 35 as one of the multipliers she took 53. As a result, the product went up by 540. What is the new product? |
A) 1566
B) 1590
C) 1560
D) 1490
Correct Answer: B
Solution :
| \[y=35x\] ... (i) |
| Then, \[y+540=53x\] ...(ii) |
| On subtracting Eq. (i) from Eq (ii), we get |
| \[540=18x\]\[\Rightarrow \]\[x=30\] |
| and \[y=35\times 30=1050\] |
| \[\therefore \]Required product |
| \[=y+540=1050+540=1590\] |
