The ages of Ram and Shyam are in the ratio 2 : 1. After five years, the ratio of their ages will be 3 : 2. Their present ages are:
Suppose present ages of Ram and Shyam are 2x and x years respectively.
or 4 x + 10 = 3x + 15
or x = 5
Hence, the present age of Ram = 10 years.
and present age of Shyam = 5 years
Study the following graph and answer the questions that follow.

A rectangle ABCD is inscribed in a circle with centre O. If AC is the diagonal and ∠BAC = 30°, then the radius of the circle will be equal to:
Join B and O
Then ∠BOC = 2 ∠BAC = 60°
Draw OM ⊥ from O on BC then BM = 
∴ ∠BOM = 30°
From ∆ BMO
∴ OB = 2 BM
So radius of circle will be equal to BC.
A hollow sphere of external and internal diameters 8 cm and 4 cm respectively, is melted into a cone of base diameter 8 cm, then the height of the cone will be equal to:
The volume of the cone formed = 
Therefore
Hence, the height of the cone formed is 14 cm.
The value of sin θ + sin (θ + 120°) + sin (θ + 240°) is equal to:

from the figure, AB, = 
A mixture of 70 litres contains milk and water in ratio of 3 :4. How many litres of milk must be added to the mixture so as to make the ratio 5 : 4?
Milk : Water
New ratio 5 : 4
Old ratio 3 : 4
Difference 2 : 0
Sum of old ratios = 3 + 4 = 7
∴ Milk added = (2/7)×70=20 litres.
A man rows boat to a place covering 72 km distance and back in 15 hours. He finds that he can row 3 km with the stream in the same time as 2 km against the stream. Find the speed of the stream.
∴ Time taken to row downstream : Time taken to row upsteam = 2 : 3
But, total time taken = 15 hours.
∴ Time taken to row downstream = 
And time taken to row upstream = 15-6 = 9 hours.
∴ Speed downstream = 
And speed upstream = 
∴ Speed of the stream = 
In an examination A gets 10% marks less than B and B gets 25% marks more than C and C gets 20% marks less than D. If A gets 270 marks in 500 then D get-
A : B = 9:10
B : C = 5 : 4
C : D = 4 : 5
A : B : C : D = 9 : 10 : 8 : 10
9 = 270
10 = 300
If from the top of a light house 100 metre high the angle of depression of a boat is tan-1(5/12), then the distance (in metre) between the boat and the light house is equal to:
and the angle of depression of the boat is tan-1 
x = 240
∴ The distance between the boat and the light house is 240 m.

The average of three numbers is 40. The first number is twice the second and the second one is thrice the third number. The difference between the largest and the smallest numbers is?
∴ second number = 3x
First number = 6x
⇒ 10x = 120 ⇒ x = 12
∴ required difference
= 6x - x = 5x = 5 x 12 = 60

Study the following graph and answer the questions that follow.
No. of candidates admitted in two different Institution(In thousands)
What was the difference between the total number of candidates admitted in institution A in the year 2004 and 2007 together and the total number of candidates admitted in institution B in the year 2003 and 2007 together?
= 5 + 6.5 = 11.5
B in 2003 and 2007
4 + 6 = 10.0
Difference = 1500
⇒ 5y + 10 + 2x = 180°
⇒ 5y + 10 + (2 x 20) = 180°
⇒ 5y = 180° - 10 - 40 = 130°
⇒ y = 26°
Find the value of (x3+y3+z3 - 3xyz), if x +y+z = 9 and xy + yz+zx = 26:
∴ (x + y + z)2 = 92 = 81
∴ x2 + y2 + z2 + 2 × 26 = 81
∴ x2 + y2 + z2 = 81 - 52 = 29
Now, x3 + y3 + z3 - 3xyz
= (x + y + z) [(x2 + y2 + z2)] - (xy + yz + xz)]
= 9 × (29 - 26) = 27
then the value of 
is
we know that, any number multiplied by 0 always gives 0.
∴ 0 is the answer.
A carriage driving in a fog passed a man who was walking at the rate of 3 km an hour in the same direction. He could see the carriage for 4 minutes and it was visible to him upto a distance of 100 m. What was the speed of the carriage?
∴ distance travelled by the carriage in 4 min = (200 + 100) = 300 meters
∴ speed of the carriage = (300/4)×(60/1000) km/hour
=9/2 km/hour

In on a particular day, Rs.1325 are collected from passengers travelling between the two stations, then the amount collected from the second class passengers is:
53x = 1325
ஃ Amount collected from Second Class = 50x
25 x 50 = Rs. 1250
If the angles of a pentagon are in the ratio 1 : 3 : 6 : 7 : 10, then the smallest angle is:
x°, 3x°, 6x°, 7x°, 10x°
But x° + 3x° + 6x° + 7x° + 10x° = (2x5 -4) x 90°
or 27x° = 6 x 90°
or x = 20°
If a man’s age is 125% of what it was 10 years ago, but 
of what it will be after 10 years. his
