For the following questions answer them individually
An employer gives Rs. 26 per day to an employee on duty and deducts Rs. 7 per day for his absence from the duty. If after 56 days, the employee receives 829, for how many days was the employee absent ?
What will come in place of the question mark (?) in the following questions ?
$$14^{\frac{5}{2}}\times42^{\frac{3}{2}}\times21^{\frac{3}{2}}\div7^{?}=432$$
$$15 \div 12.5 \times 35 + 42.8 \times 2.5 =?^{2} + 10^{2}$$
$$32\frac{3}{4}+28\frac{1}{2}\times5\frac{1}{3}-12\frac{1}{6}=?+5\frac{1}{4}$$
$$16\frac{5}{7}\times2\frac{4}{5}+15\frac{3}{10}\times8\frac{2}{9}=?$$
$$\frac{4}{9}of\frac{3}{16}of\frac{6}{13}of ?=155$$
