Question

A 210g mixture of sand and cement contains 60g of cement. Find the amount of cement in 350g of mixture.​

Answer 1

Answer:

Step-by-step explanation:

210 g mixture of sand cement contain 60 g of cement

By unitary method 350 g mixture of sand cement contain  

60/210 x 350 =  100 g.

Therefore the amount of cement in 350 g mixture is 100 g .

Answer 2

Answer:

Direct proportion =  = 100 g

Step-by-step explanation:

Due to Direct proportion

x1 = 210      y1 = 60

x2 = 350    y2 = ?

x1/y1 = x2/y2

Amount of cement in m350 g mixture = $\frac{60 X 350}{210}$

= 100 g
