IBPS PO Mains 2018 Paper for online practice

Let first and third numbers be ‘2x’ and ‘2a’ respectively.
Then, second number (A) =

2x+2a

2

= x + a
fourth number =

2x

2

= x
Then, five numbers are : 2x, (x+a), 2a, x, 62
ATQ,
2x + x + x + a = 127
4x + a = 127
From option (a) x + a = 64
⇒ 3x = 63
⇒ x = 21
Average of five numbers
=

42+64+2(64−21)+21+62

5

= 55
According to this, option (d) 64, 55 is the correct answer.
