Question 34
The two digit number whose ten's digit is t and unit digit is u is ___ .
Answer: 10t + u
Solution:
Given, ten's digit = t, unit digit = u
Required number = 10 × ten's digit + 1 × unit digit
∴Required number =(10×t)+u=10t+u
If the digit 1 is placed after a two digit number whose tens digit is ‘t’ and units digit is ‘u’, which of these options represents the new number?
