Mark (✓) against the correct answer
What per cent of 1 day is 36 minutes?

(a) 25%
(b) 2.5%
(c) 3.6%
(d) 0.25%

Answer 1

(b) 2.5%

Let x % of 1 day be 36 min.
Then, $\left(\frac{x}{100}\times 1\times 24\times 60\right)$ min = 36 min
∴ x = $\left(\frac{36\times 100}{24\times 60}\right)$ = $\left(\frac{3\times 5}{2\times 3}\right)\%=\left(\frac{5}{2}\right)\%=2.5\%$

Hence, 2.5% of 1 day is 36 min.
