Answer 1

Given :-

→ a + b * b = c ---------------- Equation 1

→ d + d + b = 10 ---------------- Equation 2

→ e + e + a = 12 ---------------- Equation 3

→ a + c = 20 = 4 * e ---------------- Equation 4

→ e + 2*d * a = ?

Now, From Equation 4, we can say That,

→ 4e = 20

Dividing both sides by 4,

→ e = 5

Putting This value in Equation 3 now, we get,

→ 5 + 5 + a = 12

→ 10 + a = 12

→ a = 2.

Putting This value in Equation 4, first part now,

→ 2 + c = 20

→ c = 20 - 2

→ c = 18 .

Putting value of a & c in Equation 1 now, we get,

→ 2 + b² = 18

→ b² = 18 - 2

→ b² = 16

→ b = 4 (Taking +ve only).

Putting This value of b in Equation 2 now,

→ d + d + 4 = 10

→ 2d = 10 - 4

→ 2d = 6

→ d = 3.

Now, we have to Find :- e + d*d * a

Putting all values we get,

→ 5 + 3*3 * 2

→ 5 + 9 * 2

→ 5 + 18

→ 23 (Ans).

(Hope It Helps You).
