Mr A came 34 minutes before the time at which a board meeting is scheduled. Mr B arrives to the meeting 25 minutes later than Mr.C who arrived 7 minutes before the scheduled time of that board meeting. If B arrived at 11.03 am, then the time of arrival of Mr.A is

A church bell rings at regular intervals of 50 minutes. It rang at 7.00 am after that there was a technical problem with the bell and it was rectified at 8.45 am. When will the bell rig between 10 am and 11 am?

For $$\frac{a}{b} < 1$$, define a * b $$= \frac{a}{b} + \frac{a^{3}}{b^{3}} + \frac{a^{5}}{b^{5}} + $$... then 4 * 6 =

If $$x \triangle y = \mid x \mid y+ x \mid y \mid - (x+y)$$ for $$x, y∈ℝ$$, then $$\frac{-3}{2} \triangle \frac{1}{2}=$$

If $$\alpha, \beta, \gamma$$ and $$\delta$$ denote the arithmetical operations $$+, - , \times$$ and $$\div$$ respectively then $$[(10 \gamma 4) \alpha (4 \gamma 4)\beta 6] \delta (50) =$$

$$\left\{ 3 - \left\{ 1 - (1 -x^{2})^{-1}\right\}^{-1}\right\}^{\frac{-1}{2}}$$

If $$\frac{(2^{n+1})^{m} (2^{2n})(2^{n})} {{(2^{m+1})^{n} (2^{2m})}} = 1$$, then m =

If $$a : b = 3 : 7$$ and $$b : c = 5 : 4$$, then $$2a : 3b : 4c =$$

Four men can do as much work as eight women, and three women can do as much work as four children. If twenty-four women finish a work in 52 days, in how many days, will the same work be finished by 8 men, 4 women and 8 children?

$$\frac{2}{\sqrt{10+2\sqrt{21}}} - \frac{1}{\sqrt{12 - 2\sqrt{35}}} + \frac{1}{\sqrt{8 - 2\sqrt{15}}}$$
