A father is 30 times older than his son. 18 years later, he will be only thrice as old as his son. Father's present age in years is
F = 30 S
or, S = F/30
Also, F + 18 = 3(S + 18)
∴ F + 18 = 3( F/30 + 18)
or, F + 18 = F/10 + 54
or, F - F/10 = 36 or, 9/10 F = 36
or, F = 36 x 10/9 = 40 yrs

In Δ CEB CE = 10 cm, CB = 10 cm, EP + PB = EB = 12 cm
In Δ CEP CE = 10 cm, EP = 6 cm
CP2 = 102 - 62
CP = 8
Here h = 8 cm
Area of trapezium is = 1/2 (sum of parallel side) (height)
= 1/2 (10 + 22) (8)
= 1/2 (32) (8)
= 128 cm2
1992 has 2 odd days
1993, 1994 and 1995 have 1 odd day each
1996 has 2 odd days
1997 and 1998 have 1 odd day each.
Hence, 9 odd days = 1 week + 2 odd days
= 2 odd days

The difference between S.I and C.I on certain amount of money for 2 years at 4% is Rs 8. Find the sum
CI2 - SI2 = PR2 /(100)2
⇒ 8 = P(16) /(100)2
⇒ 80000/16 = P
⇒ P = Rs 5000

ABCD is a cyclic quadrilateral. Diagonals AC and BD meets at P. If ∠APB = 110o and ∠CBD = 30o, then ∠ADB measures
∠BPC = 180o - 110o = 70o = ∠APD
∵ ∠DBC = ∠CAD = 30o
∴ ∠ADB = 180o - (70o + 30o) = 180o - 100o = 80o

A cistern is filled in 5 hrs and it takes 6 hrs when there is a leak in its bottom. If the cistern is full, in what time shall the leak empty it?
Let the leak empties the tank in x hours
Then 1/5 - 1/x = 1/6
1/x = 1/5 - 1/6 = 1/30
∴ The leak will empty the tank in 30 hours
If a - b = 3 and a2+b2 = 29, find the value of ab.

Let PQ = 64 km A man starts from P and walks 32 km on first day, on second day he walks only 16 km, on third day he walks 8 km, on fourth day he walks just half, i.e. 4 km. He will reach Q in
Distance between PQ = 64 km
Distance covered on the 1st day = 64/2 = 32 km
Distance covered on the 2nd day = 32/2 = 16 km
Like wise Total distance covered = 32 + 16 + 8 + 4 + ..........
This is an infinite geometric series whose first term is 32 and common ratio = 1/2
∴ Sum of the infinite series = a/1 - r
Where a is the first term and r common ratio = 32/1/2 = 64
Hence the man will never reach Q
A can finish a work in 18 days and B can do the same work in 15 days. B worked for 10 days and left the job. In how many days, A alone can finish the remaining work?

Remaining work = 1 - 2/3 = 1/3
1/3 work is done by A in = 18 x 1/3 = 6 days
