SOLUTIONS

S1. Ans.(c)
Sol.
Amount = P[1+R/100]^2
=12500 [ 1+20/100]^2=Rs 18000

S2. Ans.(a)
Sol.
(4/5+9/2)÷(1/2-1/5)
=((8+45)/10)÷((5-2)/10)
=53/10×10/3=53/3

S3. Ans.(d)
Sol.
Product of two no.’s = LCM × HCF
x × 70 = 420 × 35
x = 210

S4. Ans.(c)
Sol.
Let CP of 1 chair be x and CP of 1 table be y
ATQ,
5x + 4y = 530 ..(i)
3x + 2y = 290 ..(ii)
Solving (i) & (ii)
x = 50 y=70
∴ 6x + 3y = 6 × 50 + 3 × 70
= 300 + 210
= Rs 510

S5. Ans.(b)
Sol.
Work will be completed by both in 30/5 = 6 days
Alternate,
A and B one day work = 1/10+1/15=5/30
A and B can complete the work in 30/5=6 days

S6. Ans.(a)
Sol.
31 × 2 + 38
= 62 + 38 = 100

S7. Ans.(d)
Sol.
(5+3+6+9+11+19+3)/7=56/7=8

S8. Ans.(c)
Sol.
Let no.’s be 2x, 3x, 5x
ATQ,
10x/3=1200
x = 360
Largest no. = 5x = 1800

S9. Ans.(c)
Sol.
SP = 1200 × 120/100=Rs 1440

S10. Ans.(c)
Sol.
Let speed of boat in still water be x km/h
ATQ,
x – 10 = 50
x = 60 km/h
Downstream speed = 60 + 10 = 70 km/h
