33 years
30 years

None of these
Can’t be determined
Solution:
Let the present age of father and Son be x & y years respectively.
∴ x – 5 = 5 (y-5)
⇒ 5y – x = 20 …..(i)
and, x = 3y …….(ii)
so, from (i) and (ii)
y = 10 years and x = 30 years.

Q8. In what time would a cistern be filled by three pipes which diameters are 2 cm, 3 cm and 4 cm running together, when the largest alone can fill it is 58 minutes? The amount of water flowing in each pipe is proportional to the square of its diameter:
36 minutes
32 minutes
23 minutes
28 minutes
None of these
Solution:
Amount of water from three pipes is 4 units, 9 units and 16 units.
Let capacity of cistern be x units.
∴ x/58 = 16
⇒ x = 928 units.
In 1 minute quantity to be filled by 3 pipes = 29 units
∴ Total time required = 928/29 = 32 minutes
