## Slot -1 – Quantitative Aptitude – Arithmetic – Profit and Loss – Two types of tea, A and B, are mixed

Two types of tea, A and B, are mixed and then sold at Rs. 40 per kg. The profit is 10% if A and B are mixed in the ratio 3:2, and 5% if this ratio is 2:3. The cost prices, per kg, of A and B, are in the ratio?

a) 19:24
b) 18:25
c) 21:25
d) 17:25

Solution:

When A and B are mixed in the ratio 3:2, CP = (3A+2B)/(5 )=40/1.1

3A +2B = 2000/11 ——-1)

When A and B are mixed in the ratio 2:3, CP = (2A+3B)/(5 )=40/1.05

2A +3B = 20000/105 = 4000/21 ———–2)

By solving eq 1) & 2)

A = 7600/21*11 and B = 9600/21*11

Thus A:B = 19:24

Option a) 19:24 is correct.
