Solutions
S1. Ans.(b)
Sol. Let 5 women will complete the work in x days
Using Statement II
M1D1 = M2D2
5*x = 8*12
X = 19(1/5) days
S2. Ans.(e)
Sol. Using Statement I
Let the present ages of Ram and Shyam be 4x and 3x respectively.
Using Statement II
4x = 3x + 7
X = 7
Therefore, Shyam’s age after 6 years = 3x + 6 = 21 + 6 = 27 years
S3. Ans.(d)
Sol. The data in both the statements I and II are not sufficient to answer the question
S4. Ans.(a)
Sol. Using Statement I:
Profit = SP – CP = 40
S5. Ans.(c)
Sol. Required Probability = 7C2/12C2 = (7×6)/(12×11)=7/22
S6. Ans.(d)
Sol. Event (when sum is 7) = (1,6), (2,5), (3,4), (4,3), (5,2), (6,1)
Required probability = 6/36=1/6

S7. Ans.(b)
Sol. The number of males working at level III = 228
S8. Ans.(e)
Sol. Required Probability = 163/117*100=139.32%
S9. Ans.(d)
Sol. The number of females working at level V = 102
S10. Ans.(a)
Sol. Required Probability = 136/1500*100=9.07%
S11. Ans.(e)
Sol. I. x^2+x-20=0
(x+5)(x-4)=0⇒x=-5,4
II. y^2-y-30=0
(y-6)(y+5)=0⇒y=6,-5
∴ No relation
S12. Ans.(b)
Sol. I. 225x^2-4=0
x^2=4/225⇒x=±2/15
II. √225 y+2=0
15y+2=0⇒y=(-2)/15
S13. Ans.(e)
Sol. I. 4/√x+7/√x=√x
4+7=x ⇒x=11
II. y^2-(11)^(5/2)/√y=0
y^(5/2)-(11)^(5/2)=0
y=11
∴x=y
S14. Ans.(e)
Sol. I. x^2-10x+24=0
(x-4)(x-6)=0
x=4 or x=6
II. y^2-9y+20=0
(y-4)(y-5)=0
y=4 or y=5
No Relation
S15. Ans.(d)
Sol. I. x^2=961
x=√961
x=±31
II. y=√961
y=31
So, x<=y
