Question

) While painting a wall Rhythm has to make green paint by mixing blue, yellow and white paints
in the ratio 2 : 5 : 1. Help Rhythm to find out the quantity of blue, yellow and white paint if he requires 64 litres of green paint.

Answer 1

Given -

• Total green paint required = 64ltr

• Ratio of blue, yellow and white paint = 2:5:1

To find -

• Quantity of blue, yellow and white paint to make green paint.

Solution -

Let the common ratio be "x"

Then,

2 = 2x

5 = 5x

1 = 1x

On substituting the values -

→ 2x + 5x + 1x = 64

→8x = 64

→x = $\cancel{\dfrac{64}{8}}$

→ x = 8

Finding the quantities -

• Blue paint = 2x = 2 × 8 = 16ltr

• Yellow paint = 5x = 5 × 8 = 40ltr

• White paint = 1x = 1 × 8 = 8ltr

Verification -

By placing 8 in place of x then -

2(8) + 5(8) + 1(8) = 64

16 + 40 + 8 = 64

64 = 64

LHS = RHS

Hence, proved !

$\therefore$ Rhythm require 16ltrs of blue paint, 40ltrs of yellow paint and 8ltrs of white paint.

Answer 2

Answer:

question :-

While painting a wall Rhythm has to make green paint by mixing blue, yellow and white paints

in the ratio 2 : 5 : 1. Help Rhythm to find out the quantity of blue, yellow and white paint if he requires 64 litres of green paint.

Given :-

Total green pain required = 64 l

Ratio of blue, yellow and white paint = 2:5:1

To find -

Quantity of blue, yellow and white paint to make green paint.

Solution :-

Let the common ratio be "x"

2 = 2x

5 = 5x

1 = 1x

On substituting the values :-

→ 2x + 5x + 1x = 64

→8x = 64

→x =  

→ x = 8

Finding the quantities :-

• Blue paint = 2x = 2 × 8 = 16 ltr

• Yellow paint = 5x = 5 × 8 = 40 ltr

• White paint = 1x = 1 × 8 = 8 ltr

Verification :-

By placing 8 in place of x then :-

add them =

2(8) + 5(8) + 1(8) = 64

16 + 40 + 8 = 64

64 = 64

LHS = RHS

Hence, proved !

Rhythm require 16 ltrs of blue paint, 40ltrs of yellow paint and 8 ltrs of white paint.
