Solutions:
- Ans (c)
Total runs = 60×50 = 3000 runs
After excluding two innings.
Total runs = 48×58 = 2784 runs
H + L = 216, and H – L = 180
Lowest (L) = 18runs - Ans (c)
Salary spends in Household’s item = 50%
Transport = 50% of remaining salary
Entertainment and sports = (10 + 5) %
Remaining salary Household’s item = 50%
Transport = 50%
Entertainment and sports = 85%
Now, 1/2 * 1/2 * 17/20 * total salary = 1020
Total salary = Rs. 4800
Expenditure on transport = 4800 * 1/2 * 1/2 = Rs. 1200 - Ans (c)
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 - Ans (d)
1 day work when they work together
= 1/2(1/15 + 1/20 + 1/12) = 1/2{(4 + 3 + 5)}/60 = 1/2 * 12/60 = 1/10
Together they can complete in 10 days.
A's alone one day work = (1/10 - 1/20) = 1/20
A can alone complete this task = 20 day - Ans (c)
l = √(52+122) = 13
Curved surface area = π* r * l = π* 12 * 13 =156 π - Ans (c)
Using Statement, I & II
Speed = 350/12 = 29.16 m/s
Using Statement, II & III
Speed = (350*2)/36=19.45 m/s - Ans (b)
From Statement I
(10x+y) - (10y-x) = 27
x-y = 3
From Statement II
X : y = 5 : 2
From statement III
x-y = 3
So the digit can be obtained by Either I and II together or II and III together - Ans (c)
The required answer can be obtained by using both Statement I & II,
Statement III is irrelevant. - Ans (c)
From Statement III
Perimeter = 4a = 56
a = 14
Area = a*a = 14*14 = 196 - Ans (d)
From Statement I
4800 = P*R*2/100
PR = 240000
From Statement II
Difference = (PR^2)/〖100〗^2 =192
R = 8%
From Statement III
2P = P*R*25/100
R = 8%
