Question

Evaluate the following :

$\left(\frac{2}{3}\text{of}72\text{cm}\right)+\left(0.75\text{of}2m\right)$ $-$ $\left(0.4\text{of}3m\right)$.

• A. $60$ cm
• B. $78$ cm
• C. $44$ cm
• D. $85$ cm

Answer 1

Answer: (B)

$78$ cm

The value of $\left(\frac{2}{3}\text{of}72\text{cm}\right)+\left(0.75\text{of}2\text{m}\right)-\left(0.4\text{of}3\text{m}\right)$ is

$=(\frac{2}{3}\times 72+0.75\times 200-0.4\times 300)$ cm
$=(48+150-120)$ cm
$=78$ cm
