(d) 75% of 1 Kg​

Answer 1

Answer :-

a) 15% of ₹ 250

$\sf = \frac{15}{10 \cancel0} \times 25\cancel0$

$\sf = 37.5$

➩ 15% of ₹ 250 = ₹ 37.5

⠀

⠀

b) 120% of 2500

$\sf = \frac{120}{25\cancel{00}} \times 1\cancel{00}$

$\sf = 3000$

➩ 120% of ₹ 2500 = ₹ 3000

⠀

⠀

c) 10% of ₹ 1000

$\sf = \frac{10}{1\cancel{00}}\times 10\cancel{00}$

$\sf = 100$

➩ 10% of ₹ 1000 = ₹ 100

⠀

⠀

d) 75% of 1 kg

$\sf = \frac{75}{1\cancel{00}} \times 10\cancel{00} g$

$\sf = 750$

➩ 75% of 1 kg = 750 g

$\huge\sf\color{purple}\underline{\underline{Answer}} :$

(a) 15% of ₹250

$\sf \frac{15}{10\cancel{0}}× 25\cancel{0} \\ \sf \frac{375}{10} \\ ⟹ \color{green} \boxed{₹ 37.5}$

(b) 120% of ₹ 2500

$\sf \frac{120}{1\cancel{00}}× 25\cancel{00} ⟹\sf {300}\\ ⟹ \color{green} \boxed{₹ 300}$

(c) 10% of ₹1000

$\sf \frac{10}{1\cancel{00}}× 10\cancel{00} ⟹ \sf 100 \\ ⟹ \color{green} \boxed{₹10}$

(d) 75% of 1Kg

$\color{red}\boxed{1Kg=1000g}$

$\sf \frac{75}{1\cancel{00}}× 10\cancel{00} ⟹ \sf 75 \\ ⟹ \color{green} \boxed{75g}$
