Question

Using Urdhav Triyak Sutra calculate $28\times 32=?$

• A. 896
• B. 696
• C. 686
• D. 786

Answer 1

The correct option is A 896

2 8
x 3 2
_________________
2x3 / 2x2 + 3x8 / 8x2
6 28 16
6 29 6
8 9 6 $\Rightarrow 28\times 32=896$

1. Multiply the digits at one's place. Thus (8 x 2 = 16) and write it at the unit place of the product. (Carry over 1)
2. Cross multiply and add the products. Thus (2 x 2 + 3 x 8 = 28). Add the carry over 1 to 28 = 29 Write it at ten's place.(Carry over 2)
3. Multiply the last digits (here the digits at ten's place). Thus (2 x 3 = 6). Add the carry over 2 to 6 = 8. Write it at hundred's place.
