IBPS Clerk Prelims Model Paper 18

From statement I, if length = x m
breadth = y m, then
y =

1×2

4

(x+y)
⇒ 2y = x + y ⇒ y = x
∴ x2 =144
x = 144 = 12 m
Area of field = (16)2–(12)2 = 256 –144
= 112 m2
From statement II and III,
Length = 3x m
Breadth = 2x m
Area of rectangular field = 216
∴ 3x × 2x = 216
⇒

316

6

= 36
x = 6
∴ Length = 18 m
Breadth = 12 m
Area of the field with boundary
= (18+2 × 2)(12 + 2 × 2) = 22 ×16
= 352 m2
∴ Area of boundary = 352-216 = 136 m2
Hence,
statement I or statement II and III are sufficient to answer the question.
