A) 4
B) 2
C) 7
D) Cannot be determined
E) None of the above
Correct Answer: C
Solution :
| Let the number of Rs. 2 coins be \[x.\] |
| Then, number of Rs. 5 coins \[=x-5\] |
| According to the question, |
| \[2x+5\,\,(x-5)=50-26\] |
| \[\Rightarrow \] \[7x-25=24\] |
| \[\Rightarrow \] \[7x=49\] |
| \[\therefore \] \[x=7\] |
