Find the ratio of,

(i) Seema’s earnings to their total savings.

(ii) Prakash’s earnings to Seema’s earnings.

Answer 1

Answer:

(i) 120%

(ii)250%

(iii)320%

Step-by-step explanation:

(i)( seema earning/total )*100= (12000/10000)*100

(ii)(prakash earning/seema earning)*100=(30000/12000)*100

(iii) (money spent/money saved)*100=(32000/10000)*100

Answer 2

Given :

• Prakash's earning = ₹30000/ month
• Seema's earning = ₹12000/month
• Total savings = ₹10000/month

To find :

(i) Seema’s earnings to their total savings.

(ii) Prakash’s earnings to Seema’s earnings.

(iii) The money spent by them to the money saved by them.

SOLUTION :

(i) Seema's earning = ₹12000/month

Total savings = ₹10000/month

Seema's earning : Total savings = 12000 : 10000

$\sf \implies \: \dfrac{Seema's \: earning}{Total \: savings} \: \: = \: \dfrac{12000}{10000} \\ \\ \sf \implies \: \dfrac{Seema's \: earning}{Total \: savings} \: \: = \: \dfrac{12}{10} \\ \\ \sf \implies \: \dfrac{Seema's \: earning}{Total \: savings} \: \: = \: \dfrac{6}{5}$

Seema's earning : Total savings = 6 : 5

(ii) Prakash's earning = ₹ 30000/month

Seema's earning = ₹12000/month

Prakash's earning : Seema's earning = 30000 : 12000

$\sf \implies \: \dfrac{Prakash's \: earning}{Seema's \: earning} \: \: = \: \dfrac{30000}{12000} \\ \\ \sf \implies \: \dfrac{Prakash's \: earning}{Seema's \: earning} \: \: = \: \dfrac{30}{12} \\ \\ \sf \implies \: \dfrac{Prakash's \: earning}{Seema's \: earning} \: \: = \: \dfrac{5}{2}$

Prakash's earning : Seema's earning = 5 : 2

(iii) Money saved = ₹10000/month

Money spent = Total earnings - total savings

Money spent = { Prakash's earning + Seema's earning } - total savings

Money spent = ( 30000 + 12000) - 10000

Money spent = 42000 - 10000

Money spent = 32000

Money spent : Total savings = 32000 : 10000

$\sf \implies \: \dfrac{Money \: Spent}{Total \: saving} \: \: = \: \dfrac{32000}{10000} \\ \\ \sf \implies \: \dfrac{Money \: Spent}{Total \: saving} \: \: = \: \dfrac{32}{10} \\ \\ \sf \implies \: \dfrac{Money \: Spent}{Total \: saving} \: \: = \: \dfrac{16}{5}$

Money spent : Total savings = 16 : 5

(i) 6 : 5

(ii) 5 : 2

(iii) 16 : 5
