Answer 1

Given :-

_+_ = 17

+ +

_+_ = 13

= =

19 15

Solution :-

Let, columns are p,q,r and s .

so,

→ p + q = 17 ------- Eqn.(1)

→ r + s = 13 ------- Eqn.(2)

→ p + r = 19 ------- Eqn.(3)

→ q + s = 15 ------- Eqn.(4)

subtracting Eqn.(4) from Eqn.(1),

→ (p + q) - (q + s) = 17 - 15

→ p - s = 2 --------- Eqn.(5)

subtracting Eqn.(1) from Eqn.(3),

→ (p + r) - (p + q) = 19 - 17

→ r - q = 2 --------- Eqn.(6)

subtracting Eqn.(2) from Eqn.(4),

→ (q + s) - (r + s) = 15 - 13

→ q - r = 2 --------- Eqn.(7)

subtracting Eqn.(2) from Eqn.(3),

→ (p + r) - (r + s) = 19 - 13

→ p - s = 6 --------- Eqn.(8)

as we can see that,

→ Eqn.(5) = Eqn.(8)

but,

→ 2 ≠ 6

and,

→ r - q = q - r = 2 => Not possible .

therefore, question is wrong .

if we change second row add sign into subtraction , we can have a possible solution .

4 + 13 = 17

+ +

15 - 2 = 13

= =

19 15
