Answer:
WE + WT = AW ( option c is correct answer )
Step-by-step explanation:
Given data WET + WEE = AWW _ (1)
where every letter represents a unique digit from 0 to 9 and A = 3
here we need to find WE + WT = ?
⇒ (1) can be written as W E T + WEE = 3WW (∵ A = 3)
⇒ write (1) in column addition manner
W E T [ here W must be 1, for any other value
W E E we will not get 3 ]
3 WW
⇒ 1⁽⁺¹⁾ E T [ ⁽⁺¹⁾ is carried from (E+E) and it is possible
1 E E when E = 5 ]
3 1 1
⇒ 1 5⁽⁺¹⁾ T [ here ⁽⁺¹⁾ is carried from ( T + 5 )
1 5 5 therefore T+ 5 = 11 ]
3 1 1
⇒ T + 5 = 11 ⇒ T = 6
⇒ given problem 156 + 155 = 311
WET + WEE = AWW
⇒ W = 1, E = 5, A = 3 and T = 6
⇒ WE + WT = 15 +16 = 31 = AW
⇒ WE + WT = AW
