IBPS Clerk Prelims Model Paper 15

As
5 × 1.5 + 1.5 = 7.5 +1.5 = 9
9 × 2.5 +2.5 = 22.5 + 2.5 = 25
25 × 3.5 + 3.5 = 87.5 + 3.5 = 91
91 × 4.5 + 4.5 = 409.5 + 4.5 = 414
Similarly,
414 × 5.5 + 5.5
⇒ 2277 + 5.5
⇒ 2282.5
(a) ⇒ 3 × 1.5 + 1.5 = 4.5 + 1.5 = 6
(b) ⇒ 6 × 2.5 + 2.5 = 15 +2.5 = 17.5
(c) ⇒ 17.5 × 3.5 + 3.5
= 61.25 +3.5 = 64.75
