Check here below for the detailed solutions of the above problems:
ย
1).SI = 15767.50 โ 8500 = 7267.5
Time = (7267.5ร100)/(8500ร9) = 9.5 years
= 9ร1/2 years
Answer: b
ย
2). Alligation Method:
ย We get two values of x:7 and 13. But to get a viable answer we must keep in mind that the central value (10) must lie between x and 12. Thus the value of x should be 7 and not 13.
Alternate Method:
Let Arunโs income = 3x+2x=5x
Increase income = 5xร(110/100)=(11/2)x
Increased expenditure = (3xร112)/100= Rs. 84x/25
New savings=(11x/2)(84x/25) = (107x/50)
Increase in savings = (107x/50)2x=7x/50
Percentage increase in savings
=(7x/50ร2x)ร100 = 7%
Answer: c
ย
3). Let the distance be D km.
D/60=40 minutes = 40/60 = 2/3
Or D=(2/3)ร60 = 40 Km
Let the required speed be x kmph.
Now xร1/2=40(30 minutes=1/2 hours)
X=80 kmph
Answer: b
ย
4). Let AOB be the sector. Then the perimeter of the sector AOB = 17.4 cm
Or, OA+OB+ arc AB = 17.4
Or, 6.2+6.2+ arc AB=17.4
Or, are AB = 17.4 โ 12.4 = 5 cm
Area of the sector = 1/2รlentgh of arc ร radius=1/2ร5ร6.2=15.5 cm^{2}
Answer: b
ย
5). There are 4 vowels are 4 consonants in the word ORDINATE.
We have to arrange the letters in a row such that vowels occupy odd places. There are 4 odd places 1, 3, 5 and 7. Four vowels can be arranged in these 4 odd places inย ways = 4! Ways
Remaining 4 even places viz 2,4,6,8 are to be occupied by 4 consonants. This can be done in 4! Ways.
Total no. of words in which vowels can occupy odd places = 4! ร 4! = 576
Answer: d

Answer: d

9).Total marks obtained by girls in Maths in School P = 110ร20=2200
Similarly, in School Q = 85 ร 20 = 1700
In School R = 130 ร 20 = 2600
In School S = 80 ร 20 = 1600
In School T = 135 ร 20 = 2700
Total marks obtained by boys in History in School P = 40 ร 20 = 800
Similarly, in School Q = 45 ร 20 = 900
In School R = 50 ร 20 = 1000
In School S = 40 ร 20 = 800
In School T = 65 ร 20 = 800
In School T = 65 ร 20 = 1300
Hence in School S the marks obtained by girls are twice the marks obtained by boys in History.
Answer: b
ย
10).Required difference = 135 ร 20 โ 80 ร 20 = 2700 โ 1600 = 1100
Answer: b
