Answer:
Given that:-
yellow paint cans/blue paint cans = 6 /4
∴ No. of yellow paint cans =6x
No. of blue paint cans =4x
Given that total no. of cans used =70
∴6x+4x=70
⇒10x=70
⇒x= 70 /10 =7
∴ No. of yellow paint cans used =6x=6×7=42
No. of blue paint cans used =4x=4×7=28
Hence 28 cans of blue paint were used.
