(d) 12.5%


Answers:

1: (a) Let the ages of children be x, (x + 3), (x + 6), (x + 9) and (x + 12) years.
Then, x + (x + 3) + (x + 6) + (x + 9) + (x + 12) = 50
=>  5x = 20
=> x = 4.
So  Age of the youngest child = x = 4 years

2: (a)Let x years ago the radio of their ages was 3 : 5
so According to the question
(40-x )/(60-x )=3/5
Or, 200 – 5x = 180 – 3x
or, 2x = 20
so X = 10 years

3: (b) 2P=(PX10XT)/100, T=20 years
 

4: (c) Annual Interest=315
365=(PX5X1)/100
P=7300

5: (b) 129/120= (200+r)/200, r=15%
