15, they are in the ratio 1 2/3:2 1/2
The greater of the numbers is :
(a) 27
(b) 36
(c) 64

(d) 48​

Answer 1

Answer:

None of Above

Step-by-step explanation:

Two numbers are in the ratio $1\frac{1}{2} : 2\frac{2}{3}$.

Find the greatest number when each of these is increased by 15.

$16\frac{1}{2} :17\frac{2}{3} =48:68=12:17$

Answer 2

let two no/s. are 11/2x and 22/3x

(11/2)x+15:(22/3)x+15=12/3:21/2

11x+30:22x+75=12/3:21/2

11x+30=12/3: 22x+75=21/2

33x+90: 44x+150

33x-44x : 150-90

-10x : 60

x: 60/-10

x: -6

greatest no. = 22/3x

= (22/3)*-6

= 192/3

= 64

hence 64 option (c) is the correct answer
