Ans 3. (500 )
Cost price selling price Initial cost price = 10010% on 100 = 110 s.p.
20% less on cost price of Rs 100 = 80
40% on Rs 80 = Rs112 selling price
Difference = 112 – 100 = 2
Rs 2 Rs 10
Rs 100 ?

Ans 4. (10816, 10000 )
1st part 2nd part9 year (7 year + 2 year) 7 year
So interest on 7 year is same for both
4% interest on 2 year at C.I. = 8.16
1st part = 100 + 8.16 = 108.16
2nd part = 100
Total= 108.16 + 100 = 208.16
208.16 20816

1 day workInlet pipe 12 +3
Outlet pipe 36 -1
By taking L.C.M. of 12 and 36 +3 and -1 came.
36 hours/3 hour = 12 day work of 8 pipes together
If all 8 pipes can inlet = 8 ×3 = 24
If all 8 pipes can outlet = 8 × -1 = -8
Solve it by allegation method
Work of inlet pipe work of outlet pipe
24 -8
12
20 12
Ratio of 20:15 = 5:3
Inlet pipe = 5
Outlet pipe = 3
Ans 8. (1800)
Total profit = 10070% of 100 = 70
30% of 100 = 30
A = 50000
B = 70000
Ratio of it 5:7 = 12
So Divide Rs 70 between them equally = 70
A = Rs 35
B = Rs 35
Divide Rs 30 in ratio of 5:7
A = 12.5
B= 17.5
Difference of it = Rs 5
Difference of R5 Rs 90
Rs 100 ?
RS 1800
