Answer 1

1.After considering the values given there,
the new equation will become as

$\sqrt{100 \times 2 - 60 + 4}$
$\sqrt{200 - 60 + 4}$
$\sqrt{200 - 56}$
$\sqrt{144}$
=12.

2.The answer is (C).

3. 1+1÷0.1 = 1+10 = 11.

4. 15th person shakes hand with 14 persons.
In the same way 14th person also shakes his hand with 14 persons but we shouldn't consider one person as we have already considered in first person's count

In the same way 14+13+12+11+10+9+8+7+6+5+4+3+2+1 = 105.

5.The answer is 34.

Hope this helps you.
