The difference between two numbers is 4 and their average is 6. The product of these numbers is:
Answer & explanation
Correct answer: option 3
Let two numbers are A and B
A - B = 4 ----(1)
Average = \(\frac{Sum\; of \;all\; observation }{ Total \; number\; of \;observation }\)
Sum of both A and B = 6 × 2 = 12
A + B = 12 ---(2)
On adding both 1 and 2 ,
2A = 12 + 4 = 16
A = 8
Now,
8 + B = 12
B = 4
Product of A and B = 8 × 4 = 32
The correct answer is Option (3) → 32
