A bus starts from city X. The number of women in the bus is half of the number of men. In city Y, 8 men leave the bus and four women enter. Now, number of men and women is equal. In the beginning, how many passengers entered the bus ? | [
"36",
"45",
"30",
"46"

original breadth =10
Then, original area =10×10=100
Length is halved
⇒ New length =10/2=5
breadth is tripled.
⇒ New breadth =10×3=30
New area =5×30=150
Increase in area= new area - original area

Principal = Rs. 4000, Amount = Principal + SI = Rs. 4600
SI = Amount – Principal = 4600 – 4000 = Rs. 600
Given : Principal = Rs. 4000, Time = T = 5 years and SI = Rs. 600
SI =PRT/100
600 = 4000 *R * 5/100
600 = 200R
R = 3 % p.a.
Now the new interest rate is = 3% + 3% = 6 % p.a.
