Find the value of $$\frac{1}{4}+\frac{1}{4×5}+\frac{1}{4×5×6}$$​ (rounded up to 2 decimals)

Correct option is A

Given:

$$\frac{1}{4}+\frac{1}{4×5}+\frac{1}{4×5×6}$$

Solution:

$$\frac{1}{4}+\frac{1}{4×5}+\frac{1}{4×5×6}$$

= $$\frac{1}{4}+\frac{1}{20}+\frac{1}{120}$$

=$$\frac{30+6+1}{120}$$

=$$\frac{37}{120}$$$$\approx 0.31$$

Option (A) is right.
