Answer:
A= 18, B= 12
Step-by-step explanation:
A +B= 30 -----(1)
A :B= 3 :2
From the ratio,
A ----- 3 units
B ----- 2 units
Units shall be represented by the letter u from this point forth.
Substitute into equation (1):
3u +2u ---- 30
5u ----- 30
u ----- 30 ÷5= 6
This means that 1 unit represents 6.
A
= 3(6)
= 18
B
= 2(6)
= 12
