Solutions

S1. Ans.(b)
Sol. LCM of (7, 11, 14) = 154
∴ (154 – 118) = 36 should be added.

S2. Ans.(b)
Sol. Let A complete the work in x days.
∴ B complete the work in (x + 8) days
As A is 1.5 times more different than B
∴ Ratio of the work efficiency A/B=3/2
Now, finding out the total work
3(x) = 2 (x + 8) ⇒ x = 16
Hence, total work = 16 × 3 = 48
Cycle is (3 + 2) = 5 w/2days
Work will be completed on 19th day.

Q3. Ans.(c)
Sol. d_1/d_2 =70%=7/10
Let d₁ = 7, d₂ = 10
Area of rhombus = 1/2×d_1×d_2
=1/2×7×10=35 sq units
Area of square = 10 × 10 = 100 sq units
∴ Ratio of area = 35/100=7/20

Q4. Ans.(a)
Sol. Let MP of table = Rs. 100
CP = 80/160 × 100 = 50
∴ Profit = 10/50 × 100 = 20%

Q5. Ans.(c)
Sol. A/3=B/2=C/5=K
∴ A = 3K, B = 2K, C = 5K
∴ (C + A)² : (A + B)² : (B + C)²
= (5 + 3)² : (3 + 2)² : (2 + 5)²
= 64 : 25 : 49

S6. Ans.(d)
Sol. Let the age of son 3 years ago be x
∴ According to the question,
35 × 3 + 2 × 3 = 46 × 2 + x
⇒ x = 19
∴ Present age = 19 + 3 = 22

S7. Ans.(c)
Sol. According to the question,
60 × CP = x × SP
⇒CP/SP=x/60
∴ After 20% profit x×120/100=60
⇒ x = 50

S8. Ans.(c)
Sol. Let the maximum marks be x
∴ 0.45x + 40 = 0.55x
⇒ x = 400 marks

S9. Ans.(b)
Sol.
At 2:00 pm, man 2 starts at P with a speed 15 km/hr and distance between the two being 20 km
∴ For 2 hours, this distance will be covered by man 2 with a relative speed of 5 km/hr
∴ At 4:00 pm, distance remaining will be 10 km
Now, as man 1 rests.
man 2 will cover this distance in
10/15 × 60 = 40 minutes
∴ Time will be 4:40 pm

Q10. Ans.(a)
Sol.
3A + B : A ⇒ 23 : 7
∴ A = 7 and B = 2
∴ Rate of interest = 2/7 × 100% =200/7 Join India's largest learning destination
