Answer 1

he earns= RS 80
68/5=13.6
51/2=25.5
he spents =13.6+25.5
              = 39.1
          he saves=80-39.1
                      =  40.9

Answer 2

Given : - 

Total amount he was having ⇒ ₹ 80

Amount spent on tea ans snacks ⇒ ₹  $\frac{68}{5}$

Amount he spent on his rickshaw repairs ⇒ ₹ $\frac{51}{2}$

Saved Money = ? 

Solution :-

( Total Amt. of money ) -  ( amt. spent on snacks ) + ( amt.spent on repairs ) 

⇒ 80  -  $\frac{68}{5}$ + $\frac{51}{2}$

⇒ 80 - $\frac{391}{10}$

⇒ $\frac{409}{10}$

Therefore, Amount of money he saved on that day was ₹ 40.9
