Answer:
5
Step-by-step explanation:
Let 'a' will be filled in the blank place.
⇒ 778 × 994 = ( 778 × 1000 ) - ( 778 × a ) - 778
By taking 778 as common in R.H.S,
⇒ 778 × 994 = 778 ( 1000 - a - 1 )
⇒ 994 = 778 ( 999 - a ) ÷ 778
⇒ 994 = 999 - a
⇒ 994 - 999 = -a
⇒ -5 = -a
∴ a = 5.
Verification :
⇒ 778 × 994 = ( 778 × 1000 ) - ( 778 × 5 ) - 778
⇒ 778 × 994 = 778 ( 1000 - 5 - 1 )
⇒ 778 × 994 = 778 ( 1000 - 6 )
⇒ 778 × 994 = 778 × 994.
Verified.
So, 5 will be filled in the blank space.
