Three friends A, B and C have different amounts of rupees with them. If B takes ₹7 from A, then B will have equal amount as C has. B and C together have total ₹157. How many rupees does C have ?
In the above question B+7=C
⇒ B-C= -7
Again, B+C=157
Now solving these two equation we get,
2B = (157-7) = 150
⇒ B=75
Therefore, C = 157-75 = 82
