IBPS Clerk Prelims Model Paper 11

Ratio of milk and water in Jar A = 180 L : 36 L = 180 : 36 = 5 : 1
Let, X L of mixture taken out from Jar A.
∴ Quantity of milk taken out from Jar A
= x×

and quantity of water taken out from jar A
= x×

=

Now, according to the question,

5x 6

x 6 +6

=

⇒

5x 6

(x+3) 6

=

2

⇒

5x

x+36

=

2

⇒ 10x = 5x +180
10x – 5x = 180
⇒ 5x = 180
⇒ x = 36
Hence, 36 ∠ of mixture was taken out from Jar A.
