Question 52
What least fraction must be subtracted from the square root of $$105\frac{1}{16}$$ so that the result is a whole number?
Solution
Square root of : $$\sqrt{105\frac{1}{16}}$$
= $$\sqrt{\frac{1681}{16}}=\frac{41}{4}=10\frac{1}{4}$$
Now, the least number to be divided to make it a whole number is clearly $$\frac{1}{4}$$
= $$10+\frac{1}{4}-\frac{1}{4}=10$$
=> Ans - (A)
