Question: 1
Divide Rs.671 among A, B and C such that if their shares be increased by Rs.3, Rs.7 and Rs.9 respectively the remainder shall be in the ratio 1 : 2 : 3.
(A) Rs.105, Rs.223, Rs.330
(B) Rs.110, Rs.220, Rs.336
(C) Rs. 112, Rs.223, Rs.336
(D) None of these
Ans: C
Remainder = Rs.[671 + (3 + 7 + 9)] = Rs.690.
A’s share = Rs.$$[(690 × {1}/{6}) - 3]$$ = Rs.112.
B’s share = Rs.$$[(690 × {2}/{6}) - 7]$$ = Rs.223.
C’s share = Rs.$$[(690 × {3}/{6}) - 9]$$ = Rs.336.
Question: 2
What number has to be added to the terms of 3 : 5 to make the ratio 5 : 6?
(A) 7
(B) 8
(C) 9
(D) 10
Ans: A
Let the number to be added be x.
Then, $${3 + x} / {5 + x}$$ = $${5}/{6}$$ ⇒ 6(3 + x) = 5(5 + x)
⇒ 18 + 6x = 25 + 5x ⇒ x = 7.
Question: 3
A and B ae two alloys of gold and copper prepared by mixing metal in the ratio 7 : 2 and 7 : 11 respectively. If equal quantities of the alloys are melted to form a third alloy C, then the ratio of gold and copper in alloy C will be
(A) 5 : 7
(B) 5 : 9
(C) 6 : 9
(D) 7 : 5
Ans: D
Gold in C = $$({7/9} + {7/18})$$ units = $${7}/{6}$$units.
Copper in C = $$({2/9} + {11 /18})$$ units = $${5}/{6}$$units.
∴ Gold : Copper = $${7/6} : {5/6}$$ = 7 : 5.
Question: 4
A company blends two varieties of tea from two different tea gardens, one variety costing Rs.20 per kg and the other be R.25 per kg in the ratio 5 : 4. He sells the blended tea at R.23 per kg. Find his profit or loss percent.
(A) no profit, no loss
(B) profit of 3.5%
(C) profit of 5%
(D) loss of 5%
Ans: B
Let 5 kg of the first variety be mixed with 4 kg of second variety.
Then, C.P. of 9 kg of tea = Rs. (20 × 5 + 25 × 4) = Rs.200.
S.P. of 9 kg of tea = Rs.(23 × 9) = Rs.207.
Profit = Rs.(207 - 200) = Rs. 7.
∴ Profit % = $$({7}/{200} × 100)%$$ = 3.5%.
Question: 5
Smita work in her office for 6 hour and Kajal works in her office for 7 hour 30 minutes. Find the ratio of their working hour.
(A) 2 : 3
(B) 3 : 5
(C) 4 : 5
(D) 5 : 6
Ans: C
Working hour of Smita = 6 hours.
Working hour of Kajal = 7 hours 30 minutes = $$1{1}/{2}$$hours.
Required ratio = $$6 : 7{1}/{2}$$ = $$6 : {15}/{2}$$ = 12 : 15 = 4 : 5.
