Rahul had some chocolates with him. He had just enough chocolates to distribute them among two groups of children A and B in the following manner. He distributed the chocolates among the children in group A such that each child got as many chocolates as the number of children in it.

He distributed 9 more chocolates to children in group A than in group B. If he had less than 600 chocolates, how many possibilities exist for the number of chocolates with him?

All IndiaPagalguy Meet of year 2008' is in June (which has 30 days), but Allwinforgot which day, so he asked around. Rohit said that the date was anodd number; Apurv claimed it was greater than 13. Divya declared it wasnot a perfect square, while Sonam swore it was a perfect cube. Finally,Grand-ma tells Allwin the date was less than one-fourth her(Grand-ma's)age, which Allwin knew to be 68. Yesterday Allwin learnedthat only one of them had told the truth! If the date of the All IndiaPG Meet is D (numerical value), then
