Answer 1

Step by step explanation:-

Given :-

5 of 240 = 150% of x

To find :-

x value

Solution:-

of means - multiplication

percent means = per 100

= 1/100

150% = 150/100

5 of 240 = 150% of x

5 × 240 = $\sf\dfrac{150}{100}$ x

5 ×240 = $\sf\dfrac{15}{10}$ x

5 × 240 = $\sf\dfrac{3}{2}$ x

1200 = $\sf\dfrac{3x}{2}$

Do cross multiplication

1200 × 2 = 3x

2400= 3x

x = $\sf\dfrac{2400}{3}$

x = 800

Verification:-

5 of 240 = 150% of x.

Plugging value of x

5 × 240 = 150/100 × 800

1200 = 150×8

1200= 1200

LHS = RHS

Verified !

So, value of x is 800
