Question

2. If x : y = 4: 7, find the value of
(3x + 2y) : (5x + y).
​

Answer 1

Step-by-step explanation:

Given that,

Ratio of x : y = 4 : 7

To find,

The value of (3x + 2y) (5x + y)

= Then, put x = 4 and y = 7 (as per the stated ratio)

= Then, [4 (3) + 2(7)] [5 (4) + (7)]

= Then, (12 + 14) (20 + 7)

= then, (26) (27)

= 702

Therefore, the value of (3x + 2y) (5x + y) = 702.

Answer 2

Answer:

26:27

Step-by-step explanation:

x=4 and y=7

3(4)+2(7):5(4)+7

=12+14:20+7

=26:27
