Question 13

Which of the following statement (s) is / are TRUE ?
I. $$\sqrt{676}+\sqrt{6.76}+\sqrt{0.0676}=27.76$$

II. $$\sqrt{339+\sqrt{36}+\sqrt{49}+\sqrt{81}}=19$$

Solution

I : $$\sqrt{676}+\sqrt{6.76}+\sqrt{0.0676}=27.76$$

L.H.S. = $$26+2.6+0.26=28.86\neq$$ R.H.S.

II : $$\sqrt{339+\sqrt{36}+\sqrt{49}+\sqrt{81}}=19$$

L.H.S. = $$\sqrt{339+6+7+9}=\sqrt{361}=19=$$ R.H.S.

Thus, only II is correct.

=> Ans - (B)
