Answer 1

Step-by-step explanation:

Q.(3)

$Savings =22$%

$Expenditure =78$%

$Expenditure =12750 × \frac{78}{100}$

$Expenditure= 1275 × \frac{39}{5}$

$Expenditure= 255 × 39$

$Expenditure= 255*(40-1)$

$Expenditure=10200-255=9945Rs.$

Q.(4)

$No. \: of \: absent \: students = 174$

$Total \: students = x$

$absent \: students = 6$%

$x * \frac{6}{100} = 174$

$\frac{6x}{100} = 174$

$\frac{x}{100} = 29$

$x = 2900$

$Total \: students \: in \: that \: school = 2900$
