H + L = 216, and H – L = 180
Lowest (L) = 18runs

7) Work done by A in one day is 3/2 of the work done by B in one day. Work done by B is 1/2 of the work done by C in one day. If C alone can complete the work in 9 days, in how many days will A, B and C together complete the work?
a) 6 days
b) 5 days
c) 4 days
d) 10 days

Click to View Answer
Answer c)4days
Let work done by B in one day be ‘x’
So, work done by A in one day = 3x/2
work done by C in one day = 2x
C can alone complete the work in 9 days
Total work = 9*2x = 18x
Work done by A, B and C together in one day = 3x/2 + x + 2x = 9x/2
Total days required to complete the work by them = 18x/(9x/2)= 4 days

Answer c)156 π
l = √(52+122) = 13
Curved surface area = π* r * l = π* 12 * 13 =156 π
