Answer: Option C

Explanation:

Let the amount of pulse of price Tk. 15 = x
and the amount of pulse of price Tk. 20 = y
Then the total amount of mixture = ( x + y) kg
total cost of mixture = 15x + 20y
but the price per kg of the mixture = Tk. 16.50
so, total price of (x + y) kg = 16.50(x + y)
According to question;
16.50(x + y) = 15x + 20 y
or, 16.50x + 16.50y = 15x + 20y
or, 1.50x = 3.50y
or, x/y = 3.50/1.50 = 0.7/0.3 = 7/3
so, the required ratio is 7 : 3.

Answer: Option C

Explanation:

A/Q,
x + y = 12
or, 2x + 2y = 24 ....................... (1)
2x + 4y = 32 ............................ (2)
(2) - (1) we get,
2y = 8
or, y = 4 ......(3)
Now, from (1) and (3), we get,
x + 4 = 12
or, x = 12 - 4
or, x = 8
