Question

1) If x:y = 1:2 find the value of (2x+3y) : (x+4y)

2) A bag contains ₹ 510 in the form of 50p, 25 p and 20 p in the ratio 2:3:4. Find the number of coins of each type.

3) If 2A=3B=4C, find A:B:C​

Answer 1

Answer:

8:9

Step-by-step explanation:

X=1 and Y=2

(2x+3y): (X+4)

= (2×1 +3×2) : (1+4×2)

= 2+6 : 1+8

= 8 : 9

Answer 2

Correct Answer:

x/y= 1/2

(2x+3y):(x+4y)= (2x+3y)/(x+4y)

= (2×1/2+3) / (1/2+4)

= 8/9
