Answers:
1) Answer: c)
The ratio of present age of Naveena and her son’s age = 4 : 1 (4x, x)
Naveena’s present age = (2/5)*Naveena’s father’s present age
Naveena’s father’s present age = 10x
According to the question,
x + 4x + 10x = 120
15x = 120
x = 120/15
x = 8
Naveena’s father’s present age = 10x = 80 years
Naveena’s son’s present age = x = 8 years
Required sum = 80 + 8 = 88 years
2) Answer: c)
Let the total number of girls in the class be x,
15x + (20*18) = 18*(18 + x)
15x + 360 = 324 + 18x
3x = 36
X = 12
Total girls in the class is 12
Shortcuts:
3’s = 18
1’s = 6
Total number of girls in the class = 2’s = 12
3) Answer: a)
Speed of upstream = (48*60)/63 = 40 km/hr
Speed of current : Speed of still water = 3 : 7
Speed of upstream = Speed of boat in still water – speed of Current
40 = 4x
= > x = 10
Speed of current = 30 km/hr
Speed of boat in still water = 70 km/hr
Speed of downstream= Speed of boat in still water + speed of Current
= > 70 + 30 = 100 km/hr
Speed = 100 km/hr, Time = 42 minutes
Distance = 100*(42/60) = 70 km
4) Answer: d)
Let the ratio additional amount of Q and R be 3x and 5x,
The ratio of profit of A: B: C
= [12000*12] : [15000*8 + (15000 + 3x) *4] : [18000*8 + (18000 + 5x) *4]
= 144000 : (120000 + 60000 +12x) : (144000+ 72000 + 20x)
The ratio of share of P and Q = 3 : 4
144000/(180000+ 12x) = (3/4)
192000 = 180000 + 12x
12000 = 12x
x = 1000
Q’s additional investment after 8 months = 3x = 3*1000 = Rs. 3000
5) Answer: b)
Three pipes A, B and C can fill a tank in 8 hours.
A, B and C’s 1 hour work=1/10
A, B and C’s 3 hour work= 3/10
Remaining work= 1 – (3/10) = 7/10
The remaining part will be filled by A and B in 6 hours. Then,
= > (7/10) *(A+B) = 14
= > (A+B)’s whole work= 14*(10/7) = 20 hr
(A+B)’s 1 hour work= 1/20
A, B and C’s 1 hour work = 1/10
C’s 1 hour work= (A+B+C) – (A+B)
= > (1/10) – (1/20)
= > 1/20
C can fill the tank in 20 hours.
6) Answer: b)
C.P of product D,
= > 13750*(96/100) = CP*(110/100)
= > CP = Rs. 12000
C.P of product S = 12000 + 2400 = Rs. 14400
SP of product S =14400*(13/12) = Rs. 15600
Required difference = 15600 – 10000 = Rs. 5600
7) Answer: a)
S.P of A= Rs. 6600
C.P of F = 6600*(110/100) = Rs. 7260
Required difference = 7260 – 6300 = Rs. 960
8) Answer: d)
Cost price of A, B and D = 8000*3 = Rs. 24000
Cost price of D = 24000 – 15000 = Rs. 9000
Selling price of D = 9000*(110/100) = Rs. 9900
Marked price of E = 7000*(90/100)*(100/75) = Rs. 8400
Required ratio = 9900 : 8400 = 33 : 28
9) Answer: b)
C. P of X = 13750*(96/100)*(4/5) = Rs. 10560
C.P of Y = 9600*(7/8) = Rs. 8400
Required % = [(10560 – 8400)/8400]*100 = 25 % more
10) Answer: e)
Cost price of product D
= > 13750*(96/100)*(100/110) = Rs. 12000
Average CP = (6000 + 9000 + 8000 + 12000 + 7000)/5 = Rs. 8400
Marked price of product B = 9000*(80/100)*(100/75) = Rs. 9600
Marked price of product C = 10000*(100/80) = Rs. 12500
Marked price of product E = 7000*(90/100)*(100/75) = Rs. 8400
Average MP = (9600 + 9600 + 12500 + 13750 + 8400)/5 = Rs. 10770
Required difference = 10770 – 8400 = Rs. 2370
