Question

2 numbers are in ratio 3:4 and their sum of their cubes is 307.125.find the numbers.FULL EXPLANATION REQUIRED​

Answer 1

Answer:

Cube of 3 is 27 and cube of 4 is 64 .

now ,

at the place of 3 we write 27 and at the place of 4 we write 64 .

So ,

27x + 64x = 307.125

91x = 307.125

x = 307.125/91

x= 3.375

now,

put the value -

27x = 27 × x = 27× 3.375 = 91.125

64x = 64 × x = 64× 3.375 = 216 .

Thankyou.!
