How much sugar at Rs. 9.5 a kg should be added to 17 kg of tea at Rs. 20 a kg so that the mixture be worth Rs. 13 a kg.?

1 kg

17 kg

21 kg

34 kg

Ratio in which tea and sugar should be mixed
= 20 – 13 : 13 – 9.5 = 7 : 3.5

⇒ 7 : 3.5 ⇒ 2:1 .
Let x be quantity at 9.5/kg.

∴ 2 : 1

= x : 17,

So, x = 34 kg.

Hence, option 4 is the correct answer.
