What will come in place of the question mark (?) in the following questions ?
$$(3\frac{6}{17}+2\frac{7}{34}-1\frac{9}{25})= (1) (?)^{2}$$
The given expression can be written as $$\frac{57}{17}\div\frac{75}{34}-\frac{34}{25}$$=$$?^{2}$$
$$?^{2}= \frac{57}{17}*\frac{34}{75}-\frac{34}{25}$$
$$?^{2}=\frac{2*19}{25}-\frac{34}{25}$$
$$?^{2}=\frac{38}{25}-\frac{34}{25}$$
$$?^{2}=\frac{4}{25}$$
$$=> ?= \frac{2}{5}$$
Option A is the right answer.
