Question

tow no.are in ratio 3:5of 25٪of their sum 4.20 find x​

Answer 1

Answer:

Let the two numbers be 3x and 5x respectively.

According to the given problem,

(3x-9)/(5x-9)=12/23

=> 23×(3x-9) = (5x-9)× 12

=> 69x - 207 = 60x - 108

=>9x = 207-108

=>x = 99/9 = 11

Therefore, the two numbers are (3×11) =33 and (5×11)= 55.

The smaller number is 33.

Answer 2

Answer:

(3x+5x)×25% = 4.20

8x ×25/100=4.20

2x=4.20

x =2.1

3x=6.3

5x=10.5

this is the answer
