Directions: What will come in place of question mark in the given questions? [IBPS (Clerk) Pre2015] |
\[(625.75+450.5+?)\times \frac{3}{5}=750\] |
A) 163.25
B) 173.75
C) 167.26
D) 176.25
E) 156.75
Correct Answer: B
Solution :
\[(625.75+450.5+?)\times \frac{3}{5}=750\] |
\[\Rightarrow \] \[(1076.25+?)\times \frac{3}{5}=750\] |
\[\Rightarrow \]\[1076.25\times \frac{3}{5}+?\,\,\times \frac{3}{5}=750\] |
\[\Rightarrow \] \[645.75+?\,\,\times \frac{3}{5}=750\] |
\[\Rightarrow \] \[?\,\,\times \frac{3}{5}=750-645.75\] |
\[\Rightarrow \] \[?\,\,\times \frac{3}{5}=104.25\] |
\[\Rightarrow \] \[?=\frac{5\times 104.25}{3}\] |
\[\Rightarrow \] \[?=173.75\] |
