b) <

c) <

SOLUTION

Given that, Thousands digit = 6

Thousands digit + Tens digit = 11

Tens digit = 11 - 6 = 5

Ones digit = tens digit - 5

Therefore, ones digit = 0

Given that, hundreds digit is equal to ones digit.

Therefore, hundreds digit = 0

Now, ten thousand digit is one less than tens digit

= 5 - 1 = 4

Thus, the number so formed = 46050

SOLUTION

Given that, Ones digit = 6

Tens digit = ones digit + 2

= 6 + 2 = 8

Hundreds digit is four less than ten's digit

Therefore, Hundreds digit = 8 - 4 = 4

Now, Given that thousands digit = three less than hundreds digit.

Therefore, thousands digit = 4 - 3 = 1

Hence, the number so formed is 1486

SOLUTION

Cost for constructing first building = 7 hundred thousand rupees
