Given a series of 1,2 ,5,10,17,26,37...find the sum of first 50 terms of the progression.?
if a quadratic function f(x) has a minimum value of 3 at x=1 and f(2) = 5 ,then f(5) = ?
Just one suggestion guys:-
I am not a member of DT or UDT but just to help everyone... Those who have IMS 500 book... try and solve all the Geometry and Algebra question given there. There are around 50 - 55 quality questions.. It wont take more than 2 hours and it will help to boost up your confidence...
(P.S - I am not from IMS or in any way endorsing the IMS 500 book. Those who have it in PDF format, do solve it.. I have the physical copy of the latest edition)
Yamini and Zora are standing 25 km apart. Zora starts moving towards Yamini. After 40 minutes Yamini also starts moving towards Zora. By the time Yamini covers 5 km, Zora has covered 15 km. They meet at a point 7 km from the starting point of Yamini. What is the speed of Yamini?
a) 7.5 km/h
b) 10.5 km/h
c) 17.5 km/h
d) 6 km/h
