What will come in place of the question mark (?) in the following questions ?
$$[(3024 \div 189)^{\frac{1}{2}} + (684 \div 19)^{2}] = (?)^{2}+ 459$$
$$(0.0729 \div 0.1)^{3}\div (0.081 \times 10)^{5}$$ $$\times (0.3 \times 3)^{5}=(0.9)^{?+3}$$
$$(\sqrt{?\%}of\sqrt{1464}\times5)=149.8-112$$
$$(27)^{2} \times 6 \div 9 + (7)^{3} + 71 = (?)^{3} - 431$$
In the following questions three equations numbered I, II and III are given.
You have to solve all the equations either together or separately, or two together and one
separately, or by any other method and Give answer
a: x< y=z
b: x ≤ y < z
c: x < y > z
d: x = y > z
e: x = y = z or if none of the above relationship is established
I. 7x+ 6y+ 4z= 122
II. 4x + 5y + 3z = 88
III. 9x + 2y + z = 78
I. $$x=\sqrt{[(36)^{\frac{1}{2}}\times(1296)^{\frac{1}{4}}}]$$
II. $$2y + 3z = 33$$
III. $$6y + 5z = 71$$
I. 8x+ 7y = 135
II. 5x + 6y = 99
III. 9y + 8z = 121
I. $$(x+ y)^{3} = 1331$$
II. $$x-y+z= 0$$
III. $$xy = 28$$
