Question

A grocer mixes two varieties of tea worth ₹120/kg and ₹125/kg in a ratio to produce a new variety worth ₹122/kg. What is the ratio of the varieties to be mixed to obtain the new variety?

• A. 2 : 5
• B. 4 : 4
• C. 1 : 3
• D. 3 : 2

Answer 1

Answer:

D. 3 : 2

Use the allegation method.

Cheaper tea = ₹120/kg
Costlier tea = ₹125/kg
Mean price = ₹122/kg

Difference:

• (125 - 122 = 3)

• (122 - 120 = 2)

So the ratio of ₹120 tea : ₹125 tea is

3:2

Required ratio = 3 : 2
