Question 1:
Wheat worth Rs 30 per kg and Rs 42 per kg are mixed with a third variety of wheat in the ratio 1 : 1 : 2 respectively. The mixture is worth Rs 42 per kg.Find the price (per kg) of the third variety of wheat.
A. Rs 58
B. Rs 48
Feedback Since 1st and 2nd wheat mixed in equal ratio, their average price = (30+42)/2 = 72/2 = Rs 36
Let 3rd variety of wheat be Rs x per kg
So they are mixed as : (1+1) : 2 = 1 : 1
So
36.........................x
.............42............
x-42 42-36=6
so x-42/6 = 1/1
solve, x = 48
