Solutions:

Sol 1. (a) Let S.P. = Rs. 100

After commission, price = Rs. 90

CP = 100/120×90 = Rs. 75

Now, commission = 15%

Gain % = 85−75/75×100

=40/3%

 

Sol 2. (d) Total CP = Rs. 32

Total SP = 12 + 6 + 2 = Rs. 20

Loss % =12/32×100

= 37.5%

Sol 3. (c) A can complete work in 15 days.

And B will complete work in 10 days.

They together will complete whole work in =15×10/25=6 days

A and B together worked for = 6 × 2/3= 4 days

 

Sol 4. (d) Speed of downstream=9.6/36kmmin=16 km/hr

Speed of current = 1.6 km/hr

Let speed of man in still water = 𝑥

So, 𝑥 = 16 – 1.6 = 14.4 km/hr

Required time in upstream=19.2/14.4−1.6

=1.5 hours

 

Sol 5. (b) Ratio of profit of A and B = 1200:750 = 8:5

So, 1200×12/1500×𝑦 = 8/5

𝑦=6 months

x= 6 month

 

Sol 6. (d) 2πrh/2πr(r+h) = 3/5

2h = 3r

And 2πrh = 1848

2×22/7×2/3h×h=1848

h=21

 

Sol 7. (d) In 16 second distance covered by both A and B = 16 × 25 = 400 m

So length of A = 400 – 205 = 195

Required difference = 10 m

 

Sol 8. (a) Let B’s age = 𝑥

So A’s age = 𝑥−3

𝑥−5/𝑥+1=3/4

𝑥=23

A’s age = 23−3=20 𝑦𝑒𝑎𝑟𝑠

 

Sol 9. (a) Let Elena’s age = x

x + 15 = 5 (x – 5)

x = 10 years

 

Sol 10. (b) Let No. of soldiers = x

60 × x = 15x + 40 (x + 500)

60x =15x + 40x + 20000

5x = 20000

x = 4000

Sol 11. (d)

Sol 12. (b)

Sol 13. (e)

Sol 14. (b)

Sol 15. (c)
