1.

Replace A, B, C by suitable numerals

Answer»

In unit place

5 – A = 9, this involves borrowing

i.e. 10 + 5 –A = 9

15 – A = 9

15-9 = A

∴ A= 6

Now in tens place, as 1 is borrowed from hundred’s place as well as lent

B – 5 + 10 -1 = 8

B = 8-4 = 4

∴ B= 4

Now in hundred’s place as 1 is lent

C – 2 -1 = 2

∴ C= 5
