Answer:
Number of boys = 30
Number of girls = 25
Total students = 30 + 25 = 55students
1. Boys to Girls,
30/25 = 6/5 = 6:5
2. Girls to total students
25/55 = 5/11 = 5:11
3. Boys to total students
30/55 = 6/11 = 6:11
The second question of REENA is not complete ! Still, I would try;
Earns = 1,50,000
Saves = 50,000
Spends = 1,50,000 - 50,000
= 1,00,000
Ratio of savings to earnings
= 50,000/1,50,000
= 1/3 = 1:3
Ratio of Savings to spendings,
= 50,000/1,00,000
= 1/2 = 1:2
Ratio of Spendings to Earnings,
= 1,00,000/1,50,000
= 2/3 = 2:3
If you want to find other ratios , then just bring Numerator at Denominator and D at N.
