Correct Answer - 37,29

Correct option is (D) 14, 16, 18 Let three consecutive even numbers are x - 2, x & x+2. \(\therefore\) Their mean \(=\frac{(x-2)+x+(x+2)}3\) \(=\frac{3x}3\) = x But given that mean of three consecutive even numbers is 16. \(\therefore\) x = 16 Thus,...

Correct option is  C) 4

Correct option is (D) -5/9 Let the other numbr be x. Then \(x\times4=-\frac{20}9\) \(\Rightarrow\) \(x=\frac{-20}{9\times4}\) \(=\frac{-5}{9}.\)

Correct option is (D) 8 or -9 Let consecutive numbers are x and x+1. \(\therefore\) x(x+1) = 72    (Given) \(\Rightarrow\) \(x^2+x-72=0\) \(\Rightarrow\) \(x^2+9x-8x-72=0\) \(\Rightarrow\) x(x+9) - 8(x+9) = 0 \(\Rightarrow\) (x-8) (x+9) = 0 \(\Rightarrow\) x - 8 = 0 or x+9...

Correct option is  A) 112
