S and T can finish a piece of work in 50 days. They worked together for 20 days and then left. How much of the work is left?
Explanation
Work done in 20 days = 20/50 = 2/5. Work left = 1 − 2/5 = 3/5.
Find the factors of (x² + x − 42):
Explanation
Find numbers whose product is −42 and sum is +1: 7 and −6. So (x + 7)(x − 6) = (x − 6)(x + 7).
The mean of the data 1, 2, 10, 18, 3, 17, and 19 is:
Explanation
Sum = 70; n = 7; mean = 70/7 = 10.
The mode and median of the data 8, 6, 8, 7, 8, 6, 8, 7, and 6 is:
Explanation
Mode = 8 (appears 4 times). Sorted: 6, 6, 6, 7, 7, 8, 8, 8, 8 → median = 7. Hence 8 and 7.
What is the length of diagonal, if the area of a rectangle is 168 cm² and breadth is 7 cm?
Explanation
Length = 168/7 = 24. Diagonal = √(24² + 7²) = √(576 + 49) = √625 = 25 cm.
