Question

In what proportion should the two varieties of tea costing ₹ 180 per kg and ₹ 280 per kg be mixed to earn a profit of 20% by selling the mixture at the rate of ₹ 320 per kg.​

Answer 1

Answer:

2 : 13

Step-by-step explanation:

SP = 320

P% = 20

CP = 320 × 100/120 = 800/3

Now...

ratio = x : (1-x)

hence = x (180) + (1-x) (280) = 800/3

upon solving...

x = 2/15 & (1-x) = 13/15

therefore...

the ratio is 2 : 13
