Probability that girl student gets scholarship is = 0.4
Probability that boys student gets scholarship is = 0.6
Hence, Probability that girl don't get scholarship = 1-0.4 = 0.6
Probability that boy don't get scholarship = 1-0.6 = 0.4
probability that at-least one gets scholarship is = 1- (no one selected)
1 -(0.6*0.4) = 0.76
Two trains start at the same time from Gwalior and Delhi and proceed towards each other at 16 kmph and 24 kmph. respectively. when they meet it is found that one train has traveled 72 km more than the other the distance between the two stations is
let, t be the time when the trains meet each other.
so, 24t - 16t = 72
=> 8t = 72
=> t = 9
so, the distance between the two stations = 24t + 16t
= 40t
= 40*9
= 360 Km . (ans)
In last assembly elections for Delhi state, party A, B AND C fought against each other and got 28, 45 and 21 percent of total votes respectively. The remaining percent of votes went to others. For 2019 assembly election, party A urges party C to have an alliance so that they can beat party B.
Below facts hold good for 2019 election:
1. There is a 2% increase in vote percent of party B when compared to its own vote percent of 2014. Note: This 2% increase is only in comparison to Party B's vote percentage of 2014 and not on overall.
2. If Party A and C are forming an alliance then party A will loose 20% of its own vote percentage from what it has got in 2014, this vote percentage will go to others
3. Party's C vote share will remain same as 2014 with or without alliance with party A
4. Also, given that the number of voters in 2014 and 2019 are same.
Assuming an alliance between party A and C is formed, what is the vote percent difference between the party B and the alliance formed by A & C?
Gappu's great grandfather did a fixed deposit of Rs 50,000/- at the simple interest rate of 10% in 1949, grand mother also did a fixed deposit of 5,00,000/- at the simple interest rate of 8% in 1974 and father did a fixed deposit of 500,000,000/- at the simple interest rate of 7% in 1989.
All these fixed deposits are maturing in 2019. How much amount would Gappu get in 2019?
Assume that Gappu is the sole owner for these deposits made by his family ancestors. Also, assume that once invested fixed deposit's interest rate continues to be fixed at the initial rate throughout the investment tenure.
Amount of great grandfather's investment in 2019 = 50,000 + (50,000*10*70)/100 = 4,00,000
Amount of grand mother's investment in 2019 = 5,00,000 + (5,00,000*8*45)/100 = 23,00,000
Amount of father's investment in 2019 = 500,000,000 + (500,000,000*7*30)/100 = 15500,00,000
In 2019, Gappu would get = 4,00,000 + 23,00,000 + 15500,00,000 = 1552700000
