Question

A 2 digit no is such that product of digits in 18 if 36 is added to this no the digits interchange their places find the no

Answer 1

Answer:

no answer

Step-by-step explanation:

Given 2 digit number 10a+b

• ab=18
• 10a+b+36=10b+a ⇒ 9a+36=9b ⇒ a+4=b

• ab=18
• a(a+4)=18
• a²+4a -18= 0

there is no integer solution to this quadratic equation, so something is wrongly given

It would be good if the product of digits was a number in the format of n²- 4

For example if it was:

• ab=12

Then

• a²+4a-12= 0
• a=2, b=6
• 26+36=62
