Logical Reasoning Math Question:
Find the number which replaces the question mark (?).
87=57
65=33
51=10
36=25
19=?
Answer With Explanation For Logical Reasoning Math Question:
Take the first equation i.e., 87=57.
Consider this as AB=CD
Then the actual logic behind this is CD=(A*B)+1,CD=(A*B)+3,.....
i.e., 87=57 [(8*7)+1]
Lets implement this on all the given equations.
87=57 (Actual Logic: 87=57 [(8*7)+1]
65=33 (Actual Logic: 65=33 [(6*5)+3]
51=10 (Actual Logic: 51=10 [(5*1)+5]
36=25 (Actual Logic: 36=25 [(3*6)+7]
19=? (Actual Logic: 19=18 [(1*9)+9]
So, the answer is 18.
Tip: Do not look only at the first
equation (i.e.,87=57) and start thinking how it is equal to 57. Look at two or
three equations and try to find the common thing in it. In this scenario, the
common thing is CD=(A*B)+1,CD=(A*B)+3,.... You may not get it, but you will
definitely get it after practicing these kinds of questions regularly.
