Question

Cost of 5 kg of wheat is 91.50.
(a) What will be the cost of 8 kg of wheat?
b) What quantity of wheat can be purchased in 183?​

Answer 1

Answer:

a) 146.4 b) 10

Step-by-step explanation:

This is known as direct proportion

so,

we take x/y=x¹/y¹

a) 5/91.5= 8/y¹

now cross multiply

91.5 x 8 = 5y

146.40 = y

b) 5/91.5= x¹/183

= 183 x 5 = 91.5x

= 915/91.5= x

x= 10
