**Maths Questions for Entrance Exams – Ratio and Proportion with Solutions**

Ratio between two quanties is given a : b and total quantity is x

Then portion of

First quantity = [a/(a +b)]×x

Second quantity = [b/(a +b)]×x

Percentage of both quantities

% of First quantity = [a/(a +b)]×100

% of Second quantity = [b/(a +b)]×100

If a,b,c and d are in proportion then

a : b = c :d

If a,b,c and d are in inverse proportion then

a/d = c/b

**Q1.Rs 500 is distributed between A and B in the ratio of 2 : 3,find how much money A got.**

**a.Rs 100 b.Rs 200 c.Rs 400 d.300**

Ans. A got the money

= [2/(2+3)]×500

= (2/5) ×500 = Rs 200

**Q2.Anupama takes 125 minutes in walking a distance of 100 metre. What distance would she cover in 315 minutes?**

**a.152 km b.252 km c.352 km d.150 km **

Ans.Let the distance covered by Anupama is x in 315 minutes

She takes 125 minutes to cover the distance of 100m

∴125 : 100 = 315 😡

125/100 = 315/x

By the cross-multiplication,we get

125x = 31500

x = 31500/125 =252 km

**Q3.A car is travelling at the average speed of 50 km/hr. How much distance would it travel in 12 minutes?**

**a.15 km b.25 km c.12 km d.10 km**

Ans. Let the distance covered by the car is x km in 12 minutes

The car is traveling at the average speed of 50 km/hr

1 hour = 60 minutes

∴ 50 : 60 = x : 12

50/60 = x/12

60x = 600

x = 600/60 = 10 km

**Q4.The second class railway fare for 240 km of Journey is Rs 15.00. What would be the fare for a Journey of 139.2 km?**

**a.Rs 9.7 b.Rs 9.8 c.Rs 8.7 d.Rs 7.8**

Ans. Let x rupees would be the fare for a journey of 139.2 km

The second class railway fare for 240 km of Journey is Rs 15.00

240 : 15 = 139.2 😡

240/15 = 139.2/x

240x = 139.2×15

x = 139.2×15/240 = Rs 8.7

**Q5.The cost of 97 metre of cloth is Rs 242.50 What length of this can be purchased for Rs 302.50?**

**a.120 m b.121 m c.122 m d.125 m **

Ans. Let x m cloth can be purchased for Rs 302.50

The cost of 97 metre of cloth is Rs 242.50

x : 302.50 = 97 : 242.50

x/302.50 = 97/242.50

242.50 x = 302.50×97

x = 302.50×97/242.50 =29342.5/242.5 = 121 m

**Q6.11 men can dig 6 ¾ metre long trench in one day. How many men should be employed for digging 27 metre long trench of the same type in one day?**

**a.42 men b.32 men c.44 men d.45 men**

Ans.Let x men should be employed for digging 27 metre long trench in one day

Given that 11 men can dig 6 ¾ metre long trench in one day

6 ¾ m : 11 = 27 : x

27/4 : 11 = 27 : x

27/44 =27 /x

27x = 27×44

x = 27 ×44/27 = 44 men

** Q7.If 36 men can do a piece of work in 25 days, in how many days will 15 men do it?**

**a.40 days b.30 days c.45 days d.50 days**

Ans. Let the no. of days in which 15 men do the work are x days

Given that 36 men can do a piece of work in 25 days

In this case if no. of men increase then no. of days in doing the work decreases therefore men and no.of days are inversely proportional to each other.

∴36 : x= 15 : 25

36/x =15/25

15x = 25×36

x = 25×36/15 =60 days
