Right answer though! Well done RE: Aptitude Question: A student sent 120 emails in 5 days. Each day.... - Raj Mohan - 02-07-2017 Let total no.of mails = 't' Mails sent on first day = 'x' No.of mails sent more than the previous = 'k' No.of days, mails were sent ='n' nth term = 'x+(n-1)k' Sum of n terms totals down to total no.of mails sent i.e 't' t = (x)+(x+k)+(x+2k)+(x+3k)+...+(x+(n-1)k) t = (nx )+ k.n.(n-1)/2 12000 = 50x + 10.50.49/2 12000 = 50x + 12250 50x = 250 x = 5 RE: Aptitude Question: A student sent 120 emails in 5 days.
