Question

199. If A+B+C = 450 and A:B:C=3:5:7, then the value of “A” is: a. 60 b. 90 c. 120 d. 140

Answer 1

3x + 5x + 7x = 450

15x = 450

x = 450/15

x = 30

(A = 3x, B = 5x, C = 7x )

3x = 3 x 30

= 90

Therefore, A = 90

B = 150

C = 210

$\huge\boxed{\red{\bold{solution}}}$

$\underline{\purple{\bold{Given}}}$
A+B+C = 450
A:B:C=3:5:7

Let be x

A/q

3x+5x+7x=450
15x=450
x=30

for value of A

A = 3X = 3 × 30 =90✔✔
