Ley the current age of Krishna and yuvansh as-
Krishna - k
Yuvansh- y
1. Four years ago -
K-4=3(Y-4)
K-4=3y-12
Which gives k=3y-8
2. One year ago -
K-1=2(y-1)
Which gives k=2y-1
Solving eqn 1 and 2 it gives
Y=7
Substitute in the eqn to find
K=13
The diff is k-y= 13-7 = 6
Question : Directions: Select the option in which the numbers share the same relationship in the set as that shared by the numbers in the given set.

E.g.13 – operations on 13 such as adding/subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
