D 22 3575 3 : 2 60
E 13 2054 7 : 6 50
F 17 2788 20 : 21 75
G 24 3720 8 : 7 55
H 21 3360 8 : 6 80

Q1. The number of male post graduate employees in country H is 1800. If number of female post graduates increase by 50% in the next year, what % of female employees in that particular country is post graduate? (Given that all other data remain same)

Q2. In which country, is the percentage of women employees to number of employees (both male & female) is ranked third lowest?

Q3. What is the ratio between total number of male employees in countries B and H together and total number of post graduate employees in same countries?

Q4. What is the difference between average number of post graduate employees in countries A, B and D together and average number of post graduate employees in countries F, G and H together?

Q5. Which country has the 2nd highest number of average employees per office?

S1.

Sol.

Graduate = 3360×45=2688

Female graduate = 2688 – 1800 = 888

Female employee = 3360×614=1440

Female graduate next year = 888×32=1332

% of female graduate =13321440×100=92.5%

S2.

Sol.

A ⇒712×100=58.34% B ⇒516×100=31.25%

C ⇒1121×100=52.4% D ⇒25×100=40%

E ⇒613×100=46.15% F ⇒2141×100=51.22%

G⇒715×100=46.67% H ⇒614×100=42.86%

Clearly, H is the third lowest.

S3.

Sol. 1116×2880+814×33602880×65100+3360×45=1980+19201872+2688=39004560

= 65 : 76

S4.

Sol.

A ⇒2568×34=1926 F ⇒2788×34=2091

B ⇒2880×65100=1872 G ⇒3720×55100=2046

D ⇒3575×35=2145 H ⇒3360×45=2688

A + B + D = 5943 F + G + H = 6825

Diff. = 6825 – 5943 = 882

Avg. = 8823=294

S5.

Sol.

A ⇒256816=160.5 B ⇒288018=160 C ⇒231014=165

D ⇒357522=162 E ⇒205413=158 F ⇒278817=164

H ⇒336021=160 G ⇒372024=155

2nd highest avg. no. of employees per office = F

Directions (6–10): The graph suggests the no. of consumers and consumption of electricity units in five years. Electricity units are given in Lacs while the no. of consumers are given in thousand. Read the graph and answer the question.

Q6. What is the ratio of electricity consumption per consumer in 2012 to the same in 2015?

Q7. If no of consumers in 2016 is 120% more than in 2011 while the consumption remain same as in 2015, then what will be the impact of no of units consumed by a consumer in 2016 when compared to electricity consumption per consumer in 2015?

Q8. Electricity consumption in 2012 will be approximately how many times the total no. of consumer all over the years?

Q9. Total no of units in 2011 and 2013 are approximately what % more or less than Total units in 2012 & 2014 together?

Q10. In which of the following year, the ratio of unit consumtion to the no. of consumers is maximum?

S6.

Sol. 325250550375=325×375250×550=39∶44

S7.

Sol.

2016 : No. of consumers = 220100[225]=495 thousand

Electricity consumption = 550 Lacs

∴ Electricity consumption per consumer = 550×100000495×1000

= 111 units per consumer

2015 : Electricity consumption per consumer = 550×100000375000

≈ 147 units per consumer

Hence, the Impact is reduction of 36 units per consumer

S8.

Sol.

Total consumer all over the year = 225 + 250 + 300 + 350 + 375 = 1500 thousand

Desired value = 325×1000001500000=21.5 times approx

S9.

Sol.

Total units in 2011 and 2013 = 650 Lacs

Total units in 2012 and 2014 = 900 Lacs

Desired value =250900×100≈28%approx

S10.

Sol.It is clear from the graph that unit consumption is highest in 2014 while consumers-electricity units difference is maximum as well. Hence, Ratio of unit consumption to the number of consumers is maximum in 2014.
