IBPS SO Prelims Exam Model Paper 1

As these are consecutive numbers, B = A + 2, C = A + 4, D = A + 6, E = A + 8.
∴ A + B + C + D + E = 5A + 20
Since,Average of these five numbers=

Sum‌of‌these‌5‌numbers

5

As the average of the 5 numbers is 52
⇒

(A+B+C+D+E)

5

= 52
⇒ A + B + C + D + E = 52 × 5 = 260
∴ 5A + 20 = 260
∴ A = 48, ⇒ B = 50 and E = 56
∴ B × E = 50 × 56 = 2800.
