How much sugar at ₹68/kg should be added to 20 kg of tea worth ₹440/kg so that the mixture be worth ₹130/kg?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e 100 kg.
Tea = ₹440/kg
Sugar = ₹68/kg
Mixture = ₹130/kg
Differences = 440 − 130 = 310
⇒ 130 − 68 = 62
Ratio (sugar : tea) = 310 : 62 = 155 : 31 = 5 : 1
Sugar : Tea = 5 : 1
Given tea = 20 kg ⇒ sugar = 20 × 5 = 100 kg
Required sugar = 100 kg
