SOLUTIONS

S1. Ans.(d)

Sol.

6 bags + 4 books = 1400 …(i)

10 bags + 6 books = 2200 …(ii)

On, (i) × 10 and (ii) × 6

60 Bags + 40 books = 14000 …(iii)

60 bags + 36 book = 13200…..(iv)

On subtracting,

4 books = 800

1 book = 200 Rs.

6 bags = 1400 – 4 × 200

6 bags = 600

1 bag = 100

Cost of 2 bags and 6 books

= 2 × 100 + 6 × 200

= 200 + 1200

= 1400 Rs.

S3. Ans.(a)

Sol.

2 (ℓ + b) = 48

b=48/2–16

b=8cm

Area = 16 × 8

= 128 sq. cm

S4. Ans.(c)

Sol.

Efficiency Ratio

A : B = 150 : 100

= 3 : 2

Let, Total work = 3 × 16 = 48

(A+B)=48/((3+2) )

=9 3/5 days

S5. Ans.(a)

Sol.

Average speed=2XY/((X+Y) )

=(2×45×55)/((45+55) )

=4950/100=49.5 km⁄hr

S6. Ans.(b)

Sol.

Required time

=28/((9+5) )+28/((9–5) )

= 2 + 7 = 9 hr

S7. Ans.(c)

Sol.

x=180/30×100

=600

(x+y)=(600+600/3)

=800

S8. Ans.(b)

Sol.

=((20+54)/90)÷((20+36)/90)

=37/28=1 9/28

S9. Ans.(c)

Sol.

Numbers = 4, 5, 6, 7, 9, 11, 19

Median of odd number

=((n+1)/2)

=((7+1)/2)=4th

Median = 7

S10. Ans.(a)

Sol.

Let’s length of train and platform will be ℓ meter

15=2l/20

15 × 20 = 2ℓ

ℓ = 150 meter
