Question
In a certain code language, ‘NET’ is written as '78'
and 'ERA' is written as '48'. How will 'KIT' be written in that language?Solution
The logic is: Twice the sum of positional value of each letter. NET = 2 * (14 + 5 + 20) = 2 * 39 = 78 ERA = 2 * (5 + 18 + 1) = 2 * 24 = 48 Similarly, KIT = 2 * (11 + 9 + 20) = 2 * 40 = 80
The minimum value of 25 sin2 θ + 16 cos2 θ is
- If 2cosec 2 A – cot 2 A = 5 and 0 o < A < 90 o , then find the value of ‘A’.
- If sec 2P = sin² 60⁰ + sec 60⁰ - cos² 30⁰, then determine the value of (√3tan P + cot² P)
(tan 5x - tan 3x - tan 2x) = ?
If cot8A = tan(A+8˚), find the value of A? Given that 8A and A+8 are acute angles.
If (3cos A - sin A) = 2 cos (90° - A), then find the value of cot A.
Two points P and Q are at the distance of x and y (where y > x) respectively from the base of a building and on a straight line. If the angles of elevat...
If sec x + tan x = 11 then find secx?
