Question:

A vessel contains 128 liters mixture of water and milk in the ratio of 3 : 5 respectively. If ‘x’ liters water is added in the vessel, then milk becomes 60% more than water in the resultant mixture. Find the value of ‘x’?

(a) 4

(b) 2

(c) 6

(d) 8

(e) 10

एक बर्तन में पानी और दूध का 128 लीटर मिश्रण क्रमशः 3 : 5 के अनुपात में है। यदि बर्तन में ‘x’ लीटर पानी मिलाया जाता है, तो परिणामी मिश्रण में दूध पानी से 60% अधिक हो जाता है। ‘x’ का मान ज्ञात कीजिए?

(a) 4

(b) 2

(c) 6

(d) 8

(e) 10

Correct Answer: (b)

Explanation:

Water = (3/8)*128 = 48L, Milk = (5/8)*128 = 80L.
Milk = 1.6 × (Water + x) => 80 = 1.6 × (48 + x)
48 + x = 50 => x = 2 liters.

पानी = 48 लीटर, दूध = 80 लीटर.
दूध = 1.6 × (पानी + x) => 80 = 1.6 × (48 + x)
48 + x = 50 => x = 2 लीटर।
