The total number of blocks is 659.
Given that there is 9 in one's place of the total number of blocks. It is also given that the number in the hundreds place is 1 more than the number in the tens place.
If we assume x as the number on hundreds place and y as the number on tens place, then according to the question:
x=y+1 ......(1)
Also, the sum of hundreds and tens place numbers is 11.
x+y=11 ......(2)
substitute the value of x from equation (1) in equation (2)
y+1+y=11
=>2y=10
=>y=5
Now substitute the value of y in equation (1);
x=5+1
x=6
Therefore, number on the hundreds place is 6 and on the tens place is 5 and the total number is 659.
