IBPS Clerk Prelims Model Paper 16

Let cost price of a washing machine be x and cost price of a toaster
= (10500 — x)
According to question
(10500 - x)

(100−12)

100

= x×

(100+22)

100

(10500 — x) 88 = x × 122
44(10500 — x) = 61x
61x + 44x = 44 × 10500
105x = 44 × 10500
x =

44×10500

105

= ₹ 4400
Cost price of washing machine = ₹ 4400
Cost price of a toaster = (10500 — x)
= (10500 — 4400) = ₹ 6100
Hence, the washing machine is cheaper.
