SOLUTIONS
S1. Ans.(c)
Sol.
The variation between percentages
10% + 6% = 16%
So, 16% → 200
So, 100% → 200/16×100=1250
S2. Ans.(a)
Sol.
the centroid of a triangle is the point where the medians meet.
S3. Ans.(c)
Sol. After arranging all the numbers in ascending order, we get 3, 4, 5, 6, 92, 15, 22 and 35
Range = Highest value – Lowest value
= 35 – 3 = 32
S4. Ans.(c)
Sol.
Let no. is 56 and remainder is 29.
so, number is = (56 + 29)
and that is divided by 8 so, remainder is 5.
