Let present ages of father be x and of son is y years
x/y = 7/2, 2x=7y, y=2x/7
(y+5)=37/100*(x+5)
(2x/7+5)=37/100*(x+5)
(2x+35)/7=(37x+185)/100
200x+3500=259x+1295
259x-250x=3500-1295
59x=2205
x=37.37 years
Answer:
→ successive Rate of 20% for 2 Years = 2*20 + (20*20/100) = 40 + 4 = 44%.
And, when interest is compounded semi - Annually,
→ Rate = (20/2) = 10% .
→ Time = 2 * 2 = 4 Years.
So,
→ successive Rate of 10% for 4 Years = (2*10 + (10*10/100) = 21% Now, => 21*2 + (21*21/100) = 42 + 4.41 = 46.41% .
A/q,
→ (46.41%) - 44% = 482
→ 1% = (482/2.41)
→ 100% = (482/2.41) * 100 = Rs.20000 (Ans.)

Answer from Gauth math
Answer:
2285 approximately.
Step-by-step explanation:
14% = 320, so:
100% = (320/ 14) * 100
= 2285.71
Answer: 74 adult tickets were sold on Wednesday.
Step-by-step explanation:
Let x represent the number of child admission tickets sold on Wednesday.
Let y represent the number of adult admission tickets sold on Wednesday.
On Wednesday, 128 tickets were sold. It means that
x + y = 128
At the movie theatre, child admission is $6.40 and adult admission is $9.70. The total ticket sales on Wednesday was $1063.40. It means that
6.4x + 9.7y = 1063.4- - - - - - - - - - 1
Substituting x = 128 - y into equation 1, it becomes
6.4(128 - y) + 9.7y = 1063.4
819.2 - 6.4y + 9.7y = 1063.4
- 6.4y + 9.7y = 1063.4 - 819.2
3.3y = 244.2
y = 244.2/3.3
y = 74
x = 128 - y = 128 - 74
x = 54
