1. Every man or woman alive today had 2 parents, 4 grand-parents, 8
great-grand parents, 16 great-great- grand parents, 32 great, great,
great grand parents and so on. Let us take the case of Ram. Two
generations ago Ram had 2 x 2 or22, or 4 ancestors. Three generations
ago he had 2 x 2 x 2 or 23 or 8 ancestors. Four generations ago he had
2 x 2 x 2 x2 or 24 or 16 ancestors.

Assuming that there are 20 years to a generation, can you tell 400 years back how many ancestors did Ram have?

2.A cylindrical container has a radius of eight inches and a height of
three inches. Compute how any inches should be added to either the
radius or height to give the same increase in

the volume?

3. re is a piece of Mnemonic: Now I - even I, would celebrate In
rhymes unapt the great Immortal syracusan rivaled never more, who in
his wondrous lore Passed on befare,Left men his guidance How to
circles mensurate

4. It was a long drive. I drove 60 kilometres at 30 kilometres per hour
and then an additional 60 kilo metres at 50 kilometres per hour.Compute
my average speed over 120 kms

5.1, 2, 3, 4, 5, 6, 7, 8, 9 Here are the nine digits. Can you arrange
the nine digits in order from left to right and + or - signs only so as
to produce a result of 100?

2.

Increase in Height and Radius should have the same effect. Let 'x' be the increase. Then

(22/7) * 8*8*(3+x) = (22/7)*(8+x)*(8+x)*3

If you solve the above equation u get 0,16/3 as two values.

So it should be 16/3 inches.
