15 hours
10 hours
20 hours
25 hours
30 hours
Option D
Downstream speed of the boat = 10 + 2 = 12 km/hr
upstream speed of the boat = 10 – 2 = 8 km/hr
Time = 120/12 + 120/8 = 10 + 15 = 25 hours.

2. Aju and Viju can do a piece of work in 20 days and 30 days respectively. If they worked for alternate days and work starts from Aju, then how many days are required to complete the total work ?

15 days
18 days
25 days

LCM of 20 and 30 = 60
Total work = 60
efficiency of Aju = 60/20 = 3
efficiency of Viju =60/30 = 2
They worked for alternate days and start from Aju 2 days work of Aju and Viju = 3 + 2 = 5 work
12 (2 days) = 12 (5 work)
Time required to complete the work = 2 * 12 = 24 days

28
Option B
Let the ages of Aman and Suman After 5 years be 3x and 2x respectively.
Present age of Aman = (3x – 5) years
Present age of Suman = (2x – 5) years
(3x – 5) + (2x – 5) = 50
5x – 10 = 50
x= 12
present age of Aman = (3x – 5) = 31
age of Aman after 4 years = 31 + 4 = 35 years

SP of watch = rs.448
CP of watch = 448/112x * 100x = 400
