Answer 1

There are 659 blocks

Explanation:

The number of blocks has 9 in the ones place.

The number in the hundreds place is one more that the number in the tens place.

Let the number in the tens place is x.

Number in the hundreds place = 1+x

These two numbers equal 11.

ATQ,

x+1+x = 11

2x + 1 = 11

2x = 10

x = 5

No in the tens place = 5

No. in the hundreds place = 1+5 = 6

Hebnce, the number is 659.
