1. Multiplying any double digit no. with 11

EXAMPLE 3 4 X 1 1 3 7 4 (34) EXPLANATION STEP

1 Write the same no. that we have to multiply

with 11 with the same gap in between. In the

above example the number is 34. STEP 2 In the

gap that we have left, we can fill only 1

digit. And this no. will be the sum of both

digits of the no. that is to be multiplied with

11. In our example this no. will be 7,

347 So complete answer is 3 7 4

equal no of1s. EXAMPLE 1 1 1 1 X 1 1 1 1 1 2 3

PAPER

EXPLANATION In the above question, we have

equal no of 1s i.e. we have 4 1s in the

multiplier and multiplicand. So in the answer

block we will start writing no. s from 1 upto the

no. of 1s (here it is 4). And later go

backwards till 1.

Case 2 Unequal no of 1s in the multiplicand

Do Yourself 111 x 11 ? 111111 x 111

? 1111111 x 1111 ? TRY NOT TO USE PEN- PAPER

EXPLANATION In this question, multiplicand has

5 1s and multiplier has 3 1s. so the difference

of no. of 1s is 2 (5-32) Now in the answer

block we will start writing no.s from 1 and will

go upto the no. of lesser 1s i.e. 3 her. And

we also know the difference of no. of 1s that

is 2. So this no 3 will be repeated 2 more

times. And then go backwards till 1.

EXPLANATION In these questions, in the answer

block we have to write the no. 2 times which we

are multiplying with 101.
