Solution
The correct option is B Seven thousand five hundred seventy-five The number is a 4− digit number.
In a 4− digit number 2 digits are repeated, not consecutively.
The value of 5 at the hundreds place in the number will be 5×100=500.
This 500 is subtracted from the value of the digit at the thousands place and gives 6,500.
The value at the thousands place should be 500+6,500=7,000.
So the digit at the thousands place is 7 and our other digit is 5.
Let us form the 4− digit number in which 5 and 7 will not repeat consecutively.
The only way in which 5 and 7 will not repeat consecutively is 7,575.
The word form of 7,575 is seven thousand five hundred seventy-five.
