    Q3) Mr. Ganguly, the captain, distributed toffees between players of his team. The first player received 50 toffees and then one tenth of the remaining toffees available with Mr. Ganguly. The second player received 100 toffees and then one tenth of the remaining toffees available with the captain. The third player received 150 toffees and then one tenth of the remaining toffees available with the captain. The sequence continued like this till Mr.Ganguly was left with no toffee. After distributing the toffees Mr. Ganguly found that every player of his team had got the same number of toffees. How many players are there in the team including the captain?

    Q4) Sanjay bought a basket of oranges, a basket of apples, a basket of mangoes and a basket of peaches. He paid a total of Rs.790 for the baskets of fruits bought by him. While driving back to home, he realized that if he decreased the price of the basket of mangoes by Rs.4, increased the price of basket of peaches by Rs.7, multiplied the price of the basket of oranges by 3 and divided the price of the basket of apples by 2, then all the baskets would have the same price. Find the price of the basket of peaches.

    (2) Rs. 180
    (3) Rs. 95
    (4) Rs. 176

    Q19) A box contains 25 red balls and 20 blue balls. An unbiased die is rolled, if the result is an even number, then 3 red balls and 1 blue ball are taken out from the box without replacement and if the result is an odd number, then 2 blue balls and 1 red ball are taken out from the box without replacement. If the die is rolled 4 times, then what is the probability that the total number of red balls, which are taken out, is more than the number of blue balls, which are taken out ?
