-1 *1^2 +1 = 0

0 * 2^2 + 2 = 2

2 * 3^2 + 3 = 21

21 * 4^2 + 4 = 340

340 * 5^2 + 5 = 8505 - 144,72,48,36,28,24

144*(1/2) = 72

72*(2/3) = 48

48*(3/4) = 36

36*(4/5) = 28.8 - 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.
9:117:155:137:203:5Option 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 - 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 km62 km40 km36 km45 kmOption 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 - 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.
1:54:72:35:76:5Option E

Initial wages = 15*22

Wages after reduction = 11*25

Required ratio = 6:5 - 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% - 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.

R2=5x

𝑇1 = 𝑇2 = 1/2 𝑦𝑟

=>[𝑃1 × 4𝑥 × 1]/[ 100 × 2 ]= [𝑃2 × 5𝑥 × 1]/[ 100 × 2] => P1:P2 = 5:4
