6. In two alloys A and B the ratio of zinc to copper is 4:5 and 2:7 respectively. 9 kg of alloy A and 45 kg of alloy B are mixed together to form a new alloy. What will be the ratio of zinc to copper in the new alloy.
9:11
7:15
5:13
7:20
3:5
Option D
Total zinc = 9*(4/9) + 45*(2/9) = 14
Total copper = 9*(5/9) + 45*(7/9) = 40
Required ratio = 14/40 = 7:20

7. The speed of boat in still water is 24 km/hr. and the speed of the stream is 4 km/hr. The time taken by the boat to travel from A to B downstream is 36 minutes less than the time taken by the same boat to travel from B to C upstream. If the distance between A and B is 4 km more than the distance between B and C , what is the distance between A and B ?
56 km
62 km
40 km
36 km
45 km
Option A
Let AB = x+4 km
BC = x km
(x+4)/(24+4) = x/(24-4) – 36/60
=> x/20 – (x+4)/28 = 3/5
=> x =52
AB = 56 km

8. If there is a reduction in the number of workers in a factory in the ratio 15:11 and an increment in their wages in the rate 22:25, then the ratio by which the total wages of the workers should be decreased.
1:5
4:7
2:3
5:7
6:5
Option E
Initial wages = 15*22
Wages after reduction = 11*25
Required ratio = 6:5

9. Out of Rs. 50,000 that a man lends Rs.8000 at 5(1/2)% per annum simple interest and Rs. 24,000 at 6% per annum simple interest. He lends the remaining money at a certain rate of interest so that he gets total annual interest of Rs. 3680 . Find the rate of interest per annum, at which the remaining money is lent.
4%
10%
5%
11%
8%
Option B
Remaining amount = 50,000 – (8000 + 24000)
= Rs. 18,000
Let the rate of interest = r%
Now, 8000/100*(11/2) *1 + 24000*6/100 + 18000*r/100
= 3680
=> r = 10%

10. The rate of Simple Interest in PNB & UCO are in the ratio of 4:5. Krishnan wants to deposit his total savings in two banks in such a way that he receives equal half-yearly interest from both banks. Find the ratio, he should deposit in both banks PNB & UCO.
5:4
3:8
2:3
4:7
1:7
Option A
R1 =4x
R2=5x
𝑇1 = 𝑇2 = 1/2 𝑦𝑟
=>[𝑃1 × 4𝑥 × 1]/[ 100 × 2 ]= [𝑃2 × 5𝑥 × 1]/[ 100 × 2] => P1:P2 = 5:4
