Step-by-step explanation:
we find the average height of each height first,
t¹= (120+124)/2
=244/2
=122
t²= (124+128)/2
t²= 252/2
t²= 126
t³= (128+132)/2
t³= 260/2
t³= 130
t⁴= (132+136)/2
t⁴= 268/2
t⁴ =134
t⁵= (136+140)/2
t⁵= 276/2
t⁵= 138
so multiplying each height by its frequency we can find the total height, so we have..
total height= (122*7)+(126*8)+(130*13)+(134*9)+(138*3)
= 854+1008+1690+1206+414
= 5172
mean height = total height/total frequency
= 5172/40
=129.3

Answer: <u>₹759407.56</u>
Step-by-step explanation: Total No. of passengers = 400
1 Coach = 50 passengers
∴Total No. of coaches= 400/50=8 coaches.
Cost for each passenger= £23
∴Total cost for 400 passengers= 400x£23
= £9200 ( 1£=82.5443 ₹) ∴ Total cost for passengers = <u>₹759407.56</u>
Money spent per mile= 70p
∴Money spent for 200 miles= 200x70p=14000p
(1₹=100p) thus, 14000p=<u>₹140</u>
<u><em>Total profit</em></u>= <em>Money from the passengers- Money spent for fuel</em>
∴<u>₹759407.56- ₹140= ₹7,59,407.56</u>
<u>Actually I am a 9th grader and I have tried this question, so I am not sure for my answer, But I have tried my level best.</u>
