Answers :
1) Answer: a)
LCM of 16 and 20 = 80 units
(A + B)’s one day work = 5 units
(B + C)’s one day work = 4 units
A’s 6 days work + B’s 9 days work + C’s 22 days work = 80
(A + B)’s 6 days work + (B + C)’s 3 days work + C’s 19 days work = 80
(5*6) + (4*3) + C’s 19 days work = 80
C’s 19 days work = 80 – 30 – 12 = 38
C’s one day work = 38/19 = 2 units
C alone can complete the work in, (80/2) = 40 days
2) Answer: d)
According to the question,
(15 % – 10 %) of salary = 4000
5 % of salary = 4000
Total salary = 4000*(100/5) = Rs. 80000 = 100 %
Savings % = (20000/80000)*100 = 25 %
Total salary (100 %) = Expense (75 %) + Savings (25 %)
75 % = (15 % + 20 % + 10 % + X %)
X % = 75 % – 45 % = 30 %
3) Answer: d)
3 years ago, Rohit – Agila = 12
9 years hence, The ratio of Rohit and Agila = 7 : 4 (7x, 4x)
Present age of Rohit and Agila = 7x – 9, 4x – 9
According to the question,
7x – 4x = 12
3x = 12
X = 4
Present age of Rohit = 7x – 9 = 19
Present age of Rohit’s mother = 19 + 25 = 44 years
4) Answer: d)
I) x2 + 53/2 = (51/2 + 5) x
x2 – (√5 + 5) x + 5√5 = 0
x2 – √5x – 5x + 5√5 = 0
x (x – √5) – 5 (x – √5) = 0
(x – 5) (x – √5) = 0
x = 5, √5
II) y13 – (1259/2 / √y) = 0
y13 * y1/2 = 1259/2
y(13 + ½) = (53)9/2
y27/2 = 527/2
y = 5
x ≤ y
5) Answer: e)
I) 9x2 + 198x – 432 = 0
9x2 + 216x – 18x – 432 = 0
9x (x + 24) – 18 (x + 24) = 0
(9x – 18) (x + 24) = 0
x = 2, -24
II) 7y2 + 14y – 156 = 0
7y2 + 42y – 26y – 156 = 0
7y (y + 6) – 26 (y + 6) = 0
(7y – 26) (y + 6) = 0
y = 26/7, -6 = 3.71, -6
Can’t be determined
6) Answer: d)
The selling price of item R = 18000*(88/100) = Rs. 15840
The cost price of item R = 15840*(100/120) = Rs. 13200
The cost price of item P and R together
= > 20000 + 13200 = Rs. 33200
The marked price of item Q and R together
= > 15000 + 18000 = Rs. 33000
Required difference = 33200 – 33000 = Rs. 200
7) Answer: a)
The average selling price of all the given items together
= > [(20000 + 3000) + 13500 + (18000*(88/100)) + (22800*(125/100)]/4
= > [23000 + 13500 + 15840 + 28500]/4
= > 80840/4 = Rs. 20210
8) Answer: c)
The selling price of item P = 20000 + 3000 = Rs. 23000
The marked price of item P = Rs. 25000
The discount % given by the shopkeeper for item P
= > [(25000 – 23000)/25000]*100 = 8 %
The selling price of item R = 22800*(125/100) = Rs. 28500
The marked price of item R = Rs. 30000
The discount % given by the shopkeeper for item R
= > [(30000 – 28500)/30000]*100 = 5 %
Required ratio = 8 : 5
9) Answer: b)
The cost price of item Q = 13500*(100/125) = Rs. 10800
The profit of item Q = 13500 – 10800 = Rs. 2700
The total profit earned by the item P and Q together
= > 3000 + 2700 = Rs. 5700
The total profit earned by the item R and S together
= > 2640 + (22800*(25/100))
= > 2640 + 5700 = Rs. 8340
Required ratio = 5700 : 8340 = 95 : 139
10) Answer: d)
The marked price of item P and S together
= > 23000*(100/92) + 22800*(125/100)*(100/95)
= > 25000 + 30000 = Rs. 55000
The selling price of item Q and R together
= > 13500 + (13200 + 2640) = Rs. 29340
Required % = (55000/29340)*100 = 187.45 % = 190 %
