| Directions: What approximate value will come in place of question mark (?) in the given questions? (You are not expected to calculate exact value.) [IBPS (SO) IT 2015] |
| 105.27% of 1200.11 + 11.80% of 2360.85 = 21.99% of ? + 1420.99 |
A) 500
B) 240
C) 310
D) 550
E) 960
Correct Answer: D
Solution :
| 105.27% of 1200.11 + 11.80% of 2360.85 |
| = 21.99% of ? + 1420.99 |
| \[\Rightarrow \] 105% of 1200 + 12% of 2360 = 22% of ? + 1421 |
| \[\Rightarrow \] \[1260+283.2=0.22\times ?+1421\] |
| \[\Rightarrow \] \[0.22\times ?=122.2\] |
| \[\Rightarrow \] \[?\,\,=\,\,\frac{122.2}{0.22}=555.45\approx 550\] |
