There are 659 blocks
Solution:
The number in ones place is 9
Let's denote number in the tens place with x
The number in the hundreds place is one more then the tens place
Therefore,
The number in hundreds place is 1 + x
Those two numbers equal 11
Which means tens place number and hundreds place number sums up to 11
tens place + hundreds place = 11
x + 1 + x = 11
2x = 11 - 1
2x = 10
x = 5
Thus number in tens place = x = 5
Number in hundreds place = 1 + x = 1 + 5 = 6
The number is represented as:
Number = (Number in hundreds place)(number in tens place)(number in ones place)
Number = 659
Thus 659 blocks are there
