Answer:
Answer 14 Rohit bought at cheaper
Step-by-step explanation:
Rahul bought 10 pens for = Rs 80
Rohit bought 12 pens for = Rs 84
Now we find the cost of 1 pen bought by Rahul and Rohit
Rahul bought 1 pen = 80/10 = 8
Rohit bought 1 pen = 84/12 = 7
So Rohit bought pens at cheaper rate
Step-by-step explanation:
answer of Q14
Cost of 10 pens bought by Rahul = ₹80
Cost of 1 pen bought by Rahul = ₹80 ÷ 10
= ₹8
Cost of 12 pens bought by Rohit = ₹84
Cost of 1 pen bought by Rohit = ₹84 ÷ 12
= ₹ 7
Therefore, Rohit got the pens at cheaper (सस्ता) rates.
answer of Q17
Number of boys = 264
Number of girls = 250
Total number of students = 264 + 250 = 514
Now,
a) Find the ratio of number of girls to number of boys.
= 250:264

b) Find the ratio of number of boys to the total number of students.
= 264:514
= 132:257
c) Find the ratio of number of girls to the total number of students.
= 250:514
= 125:257
