Question

111. यदि x:y = 1:2 है, तो (8x+9y) : (8x+2y)
का मान क्या होगा?
(A) 22:29
(B) 29 : 22
(C) 13:6
(D) 6: 13​

Answer 1

Answer:

ans is c 13:6

Step-by-step explanation:

as if we put the value of x n y in the eqn the we will get 26:12 and ratio is also divide so this are multiple of 2 so we will get 13:6

Answer 2

Answer:

c

Step-by-step explanation:

since x/y=1/2

and (8x+9y)/(8x+2y)

Now:-

x=1 and y=2. (as x and y Are in ratio)

therefore

(8×1+9×2)/(8×1+2×2)

=8+18/8+4

=26/12

=13/6

hence (8x+9y):(8x+2y)=13:6 Ans
