Explanation :–

778 × 994 = (778 × 1000) – (778 × ___ ) – 778.

Let the missing number be 'x' .

778 × 994 = (778 × 1000) – (778 × x ) – 778.

773,332 = 7,78,000 – 778x – 778

778x = 7,78,000 – 778 – 773,332

778x = 7,78,000 – 774,110

778x = 3,890

x = 3,890 ÷ 778

x = 5

Now let's verify our answer :)

LHS (Left hand side) :

778 × 994

= 773,332

RHS (Right hand side) :

(778 × 1000) – (778 × x) – 778.

= (778 × 1000) – (778 × 5) – 778

= 778000 – 3,890 – 778

= 778000 – 4,668

= 773,332

LHS = RHS = 773,332

Hence, verified

Therefore, the value of the missing number is 5.
