Question
125 sweets were distributed equally among children in
such a way that the number of sweets received by each child is 20% of the total number of children. How many sweets did each child receivedSolution
Let the total number of children be x. Then, => x × (20% of x) = 125 => x2 = (125 × 100)/20 => x2 = 625 => x = 25 Number of sweets received by each child = 20% of 25 = 5
If tanθ = x then find the value of cos 2θ?

What is the value of [(sin x + sin y) (sin x – sin y)]/[(cosx + cosy) (cosy – cosx)]?
The value of (3tan10°-tan³10°)/(1-3tan²10°) is equal to
If 2x = cosec @ and 4/x = cot @ then the value of 2(x ² - 1/x ² ) is
If cosec (2A + B) = 2 and cosec (A + B) = 1, find the value of (3A – B).
