I. ${x^2} - 7x + 12 = 0$

II. ${y^2} - 8y + 12 = 0$

I. $2{x^2} + x - 28 = 0$

II. $2{y^2} - 23y + 56 = 0$

I. $2{x^2} - 7x - 60 = 0$

II. $3{y^2} + 13y + 4 = 0$

I. ${x^2} - 17x - 84 = 0$

II. ${y^2} + 4y - 117 = 0$

What approximate value should come in place of question mark (?) in the following question?

Note:- (you are not expected to calculate the exact value.)

$111.01 + 41.23 + {(4.96)^2} + {(2.09)^2} = ?$

$109.07sqrt ? - frac{{61}}{{21.02}} imes ? = 47.96sqrt ?$

$1332.89 + 171.928 + 17.01 + {?^2} = 1690.87$

$150.09{ m{\% ;of;}}20 + frac{{322.9}}{{17.02}} + sqrt ? = {(8.96)^2}$

$56.08;{ m{\% ;of;}}149.92 + sqrt {28.02 imes 6.98} - 11frac{1}{9}{ m{\% ;of;}}998.9 = ?$
