two numbers are 2x and 3y
now x=48/2=24
y=48/3=16
therefore 24+16=40
now x=48/2=24
y=48/3=16
therefore 24+16=40

Answer:
Option : B =40 ✔️✔️✔️
EXPLANATION :
let the no.s be 2x & 3x
L. C. M of 2x & 3x= 6x ✔️
(lcm of 2 & 3 = 6. hence LCM of 2x & 3x = 6x)
Given that LCM of 2x & 3x is 48
=>6x = 48
=>x=48/6 =8
Sum of the numbers = 2x + 3x = 5x = 5 × 8 = 40✔️
