Answer 1

here you go....☆☆

let no.=x
$\frac{22}{7} + \frac{68}{5} + \frac{51}{2} + x = 80$

taking lcm

$\frac{220 + 1360 + 1785}{70} + x = 80$

$\frac{3365}{70} + x = 80$

$48.8 + x = 80$

$x = 80 - 48.8$

$x = 31.2$

so his savings are *$31.2

*$=rupees

hope it helps you......

Answer 2

Total earning = rs. 80
spend on tea and snacks = rs. 68/5
spend on food = rs 51/2
spend on repairing = rs. 22/5
total spend = 68/5 + 51/2 + 22/5
                  = rs 435/10 = rs 43.50
total money saved on that day = 80 - 43.50
                                                 = rs 36.50
