Michael had
19 as many marbles as Vaidev. Vaidev had thrice as many marbles as Nick. If Michael had 70 marbles fewer than Nick,
- how many marbles did Michael have?
- how many marbles did they have altogether?
(a)
Number of marbles that Michael had = 1 u
Number of marbles that Vaidev had = 9 u
Number of marbles that Nick had = 9 u ÷ 3 = 3 u
Number of marbles that Michael had fewer than Nick
= 3 u - 1 u
= 2 u
2 u = 70
1 u = 70 ÷ 2 = 35
Number of marbles that Michael had
= 1 u
= 35
(b)
Total number of marbles that they had
= 1 u + 9 u + 3 u
= 13 u
= 13 x 35
= 455
Answer(s): (a) 35; (b) 455
