5) Kelynn is 5 times
as old as Janet this year.
Janet is 9 years old now.
In how many years' time will Kelynn's age be twice that of Janet?
Answers:
1) 748 000 - 29 800 = 718200
Remaining amount paid
Equal MONTHLY for 30 years
30 x 12 = 360
718 200 / 360 = $1995
Each monthly instalment
will be $1995
2) 1st week
T W T F S S = 4 2
2nd week M T W T
F S S = 5 2
3rd week M T W T
F S S = 5 2
4th week M T W T
F S S = 5 2
5th week M
= 1
Total Monday to Friday
= 20
Total Saturday to Sunday
= 8
25 x 20 = 500
30 x 8 = 240
500 + 240 = $740
She would be paid $740
3) At first:
7/11 Beads = red
Green = 1 - 7/11 = 4/11
Later:
Red bean 105 given away = 7/11
- 105 = 1/2 of green
1/2 of green = 4/11 /2 = 2/11
Therefore:
7/11 - 105 = 2/11
And:
7/11 - 2/11 = 105
5/11 = 105
1/11 = 105/5 = 21
Green beads = 4/11 = 4x21
= 84
4) Bag A = 189 marbles
Bag B = 279 marbles
279 + 189 = 468
Transferred Bag B to Bag
A until Each Bag had Same Marbles
468 / 2 = 234
279 - 234 = 45 marbles
He transfer 45 marbles
from Bag B to Bag A
5) Kelynn 5 times older = 9 x 5 = 45
Difference between
Kelynn and Janet = 45 - 9 = 36
36 = 1 unit
36 - 9 = 27 years
