Check Below for Detailed Solutions of the above Aptitude Questions:
1). Ramesh’s monthly income = 642000/12 = Rs. 53,500
Now, expenditure on household goods
= 53500×(1/5)= 10700
Remaining income = 53500-10700
= Rs.42800.
Again, expenditure on children’s school fees
= (3/8)× 428000= Rs. 16050
Remaining monthly income= 42800-16050= Rs. 26750
Again, he denotes 12% of this to NGO
Donated amount [(26750×12)/100]= Rs. 3210
Remaining amount = 26750-3210
= Rs. 23540.
Answer: d)
2). CI= P {(1+r/100)n-1}
Or, 5984=P {(I+20/100)2-1}
Or, 5984=P {(6/5)2-1} = P {(36-25)/25}
P=(5984×25)/11 =544×25 =Rs.13600
Now, SI =(P×r×t)/100 =(13600×9×6)/100 =Rs.7344
Answer: e)
3). Milk in vessel =(72/9)×5 =40 litres
Water in vessel =(72/9)×4 =32 litres
According to the question, milk in 18 litres mixture=18×(5/9) =10 litres
New mixture=(72-18+10) =64litres
Now, milk in new mixture=40-10 =30 litres
Reqd percentage of milk in the mixture =(30/64) ×100 =46×(7/8)%
Answer: a)
4). Let the number be x.
Then, (x/2) +234 =5x
Or, 5x-x/2 =234
Or, 9x =234×2
x=(234×2)/9 =52
Answer: b)
5). Reqd cost price
=100×84 =Rs.8400
Answer: c)

Area of the lawn =1386

Or,π r2= 1386

New radius including path =21+14 =35m

New area =π r=[(22/7)×35×35] =3850m2
Answer: a)
7). Let the length be 9x and the breadth be 7x
Then, 9x×7x =1008
Or,63x2 =1008
Or,x2=1008/63 =16
Now, perimeter of the rectangle
=2(l+b) =2(9×4+7×4)
= 2(36+28) =2×64 =128m2
Answer: e)
8). Downstream speed=(15.2×60)/24
=912/24 =38 kmph
Speed of the stream
=2.5 kmph
 Speed of the boat = (38-2.5)
=35.5 kmph
Now upstream speed =35.5-2.5
=33 kmph
Distance covered in 18 minutes =(33/60)×18 =9.9 km
Answer: e)
9). Let the male population in the year 2013 be 6x and the female population that year be 7x.
 Now, according to the question,
6x×(115/100) + 7x×(112/100) =5896
Or,6.9x + 7.84x =5896
Or,14.74x =5896
x=(5896/14.74) =400
Thus, the female population in 2014 =7.84×400 =3136
Answer :e)
10). Work efficiency of A to B =180:100 =9:5
When they work together they finish the work in 19×2/7 days =135/7 days
Now, B alone can finish the work in (135/7 ×14/5) =54 days
Answer: c)
