CBSE Class 10 Answered

Arrange the given numbers for multiplication as shown in figure, the boxes show the digits we should find.

As we can see we need 2 at unit place in the final answer and this will come from 9Xa.

Hence a = 8, so that finally we'll have 2 in the unit place. Hence a = 8.

Carry out multiplication by 8, and hence first row of boxes can be replaced now by 7992.

Now we need 3 at the tens place in the final answer, and that'll come from 9 + (9xb) = ***3.

Hence b has to be 6. And now we'll get the second row of boxes.

Similarly complete the multiplication, and final answer is as shown in the figure.
