Question 22

Find out the two signs to be interchanged for making following equation correct.

$$\frac{1}{4} \div \frac{1}{64} - 5 + 45 \times 120 = 5$$

Solution

If we interchange $$\times\ \ and\ \ -\ $$ sign,

$$\frac{1\ }{4}\div\frac{\ 1}{64}\times 5+45- 120$$

$$=\frac{1\ }{4}\times\ \frac{\ 64}{1}\times 5+45- 120$$

$$=16\times\ 5+45-120$$

$$=80+45-120$$

$$=125-120$$

$$=5.$$

So, Option B is correct.
