16 * 1.5 = 24,
24 * 2.5 = 60
60 * 3.5 = 210
210 * 4.5 = 945
945 * 5.5 = 51975
51975 * 6.5 = 3378.75
4. (1)
16*0.5+7 = 15
15*1+6 = 21
21*1.5+5 = 36.5
36.5*2+4 = 77
77*2.5+3 = 195.5
195.5+3+2=588.5
5. (2)
142+729 = 871

871+512 = 1383

1383+343 = 1726

1726+216 = 1942

1942+125 = 2067

2067+64 = 2131

6.  Let x be the original number of workers and Rs. y the (average) wages per workers.

Then the total wages before changes = Rs. xy.
After reduction, the number of workers = (11 x)/15
After increment, the (average) wages per workers = Rs.(25 y)/22
The total wages after changes = (11x/15) × (25y/22) =5xy/6
Thus, the total wages of workers get decreased from Rs. xy to Rs. 5xy/6
Hence, the required ratio in which the total wages decrease is xy:5xy/6 = 6:5

let earning= 4x : 5x;
expences= 7y:9y
saving = income – expences
4x-7y= 5x-9y = 50
on solving both eqn. x=100
So Daily income are Rs. 400 and Rs. 500

7.  Let us first find the cost price (C.P.) of the mixture. If S.P. is Rs. 100, profit is 17.5
Therefore C.P. = Rs. (100 – 17.5) = Rs. 82.5
If S.P. is Rs. 8.80, C.P. is (82.5× 8.80)/ 100 = Rs. 7.26
C.P. of the mixture per kg = Rs. 7.26
2nd difference = Profit by selling 1 kg. of 2nd kind @ Rs. 7.26
= Rs. 7.77 – Rs. 7.26 = 51 paise
1st difference = Rs. 7.26 – Rs. 6.92 = 34 paise
We have to mix the two kinds in such a ratio that the amount of profit in the first case
must balance the amount of loss in the second case.
Hence, the required ratio = (2nd diff) : (1st diff.) = 51 : 34 = 3 : 2.

8.  Interest= Rs. 50,000 – 46875 = Rs. 3125
1 year 8 month = 5/3 year
so 3125= (46875*r*5)/(3*100)
on solving this r = 4%

9. Sum = (50*100)/(2*5) = Rs. 500
Amount = 500(1+5/100)^2 = 551.25
interest =551.25- 500 = Rs 51.5

10. math : Physics : bio = 5:7:8
After increment 5*140/100 : 7*150/100 : 8*175/100
14:21:28= 2:3:4

11.  Remain profit  for A, B & C
7400*95/100= 7030
A:B:C= 6500*6 : 8400*5 : 10,000*3 = 39:42:30
Share of B= 7030*42/111 =  Rs. 2660

12. Present age of P+Q+R = 25*3+ 5*3= 90 year
Present age of Q+R= 20*2 + 7 *2 = 54 year
present age of P = 90-54 = 36 year.

13. let Kamal work for y months.
2100* 12 = 3600 * y ;
y = 7 months .
so duration after  kamal join = 12-7 = 5 months.

14. marked Price =800
Seling price  after discount= 800*90/100*85/100 = 612
Total price including transportation = 612 + 25 = 637
selling it to 800 there would be gain

so gain % = (800 – 637)/637 *100 = 25 % approx
