A) 35 and 15
B) 35 and 20
C) 15 and 35
D) 25 and 25
Correct Answer: D
Solution :
[d] Let the number of Rs.1 coins = x |
and number of Rs,2 coins =y |
According to the question, |
\[x+y=50\] ...(1) |
and\[(x\times 1)+(y\times 2)=75\Rightarrow x+2y=75\] ...(2) |
Subtracting eq. (1) from eq. (2), we get |
\[y=25-50=25\] |
From eq. (1), \[x+25=50\Rightarrow x=25\] |
