Answer 1

Answer:

6. 30%

7. 80%

8. 1755

9. ₹13020

Step-by-step explanation:

6.

given -

total income = ₹20,000

total spent = ₹6,000

money she spent = ₹6000/₹20000

money she spent (in %) = 6000×100/20000

= 600000 ÷ 20000

= 30%

-------------------

7.

given -

total students = 1200

students go to picnic = 240

students did not go to picnic = 1200-240 = 960

students didn't go to picnic (in %) = 960×100/1200

= 96000 ÷ 1200

= 80%

-----------------

8.

given -

students boys = 945

students girls (in %) = 65%

students boys (in %) = 100%-65% = 35%

let us think the number of total students = x

so

=> 35% of x = 945

=> 35×x/100 = 945

=> 35x = 945×100

=> 35x = 94500

=> x = 94500 ÷ 35

=> x = 2700

total students = 2700

students girls = 65% of total

= 65×2700/100

= 65×27

= 1755

---------------

9.

given -

a person's income = ₹1200

income increased = 8.5%

income after increasing = income before + 8.5% of income

= ₹12000 + ₹12000×8.5/100

= ₹12000 + ₹12000×85/1000

= ₹12000 + ₹85×12000÷1000

= ₹12000 + ₹85×12

= ₹12000 + ₹1020

= 13020
