Answer
1)total no. of people visited =10,200
2)original price=₹70,000
Step by step explanation
- Let total no. of people visited be X
- No.of people visited by metro=15% of X= 15X÷100
3.No.of people visited by taxi=10% of X= 10X÷100
4.Remaining No. of people visited by own transport=7650
5. ⇒ X = 15X÷100 + 10X÷100 + 7650
⇒ 100X = 15X + 10X + 765000
⇒ 100X - 25X =765000
⇒ 75X = 765000
⇒ X = 765000 ÷ 75
⇒ X = 10,200
2 Let original price of tv = ₹ Y
Percentage of price increased = 21% of Y = 21Y÷100
Price after increasing 21% = ₹84,700
⇒ ₹84,700 = Y + 21Y÷100
⇒ 8470000 = 100Y + 21Y
⇒ 121Y = 8470000
⇒ Y = 8470000 ÷ 121
⇒ Y = ₹70,000
