Question

Bitu spends 1/3 of the money with him on books, 1/4 of the remaining on food and 2/5 of the remaining on travel. Now, he is left with rupees 450.How much money did he have in the beginning​

Answer 1

answer = 27000

let the money he had be x

then one third of x + one fourth of x + two fifth of x + 450 = x

then take out the lcm of 3, 4 and 5 which is 60 .

20x + 15x + 12x + 27000 / 60 = x

59x + 27000= 60x

x= 27000

Answer 2

Answer:

sol?:

Let the amount of money Bitu had at the beginning be Rs x.

Now, According to question:

or, Money spend on books = 1/3 of x

                                             =x/3

also,

or, Money spend on food  = 1/4 of (x-x/3)........{i.e the remaining money}

                                           = x/6

also,

or Money spend on travel = 2/5 of (x-x/6)........{i.e the remaining money}

                                           = x/3

now,remaining money he has = Rs.450

finally,

x = x/3 +x/3+x/6+450.............................{i.e total money = spend money +                                            

                                                              remaining money}

or, x=(5x+2700)/6

or,6x-5x = 2700

or, x  = Rs 2700

So, Bitu had Rs 2700 in the beginning
