Question

lily, safia and manjit have 24 marbles altogether. manjit has the same number of marbles as lily and safia together. lily has 5 marbles. how many marbles does safia have?

Answer 1

safia has 7 marbles

Explanation:

T=24 ÷ 2 ie(L+S)

=12 for Majid

if L+S+M=24

5+S+12=24

S=24 - (12+7)

S=24 - 17

S=7

Answer 2

7

Explanation:

M = (L + S)

24/2 = 12

12-5 =7

L:5

S:7

7+5 = 12 (Manjit)

12+12= 24
