It integrates railway expertise with IT, data analytics, and AI for intelligent, scalable training systems. Sanraksha features smart learning, feedback, and real-time monitoring.Â
3x +3y =10 and 3x+y =5 then find the value of 3x-y +3y-x.
If, 3x + 2y = 15, and 2xy = 12, and 3x > 2y, then find the value of 27x³ – 8y³.
1/3 + 1/15 + 1/35 + 1/63 + 1/99 = ?
If sin 28° = 15/17 , then tan 62° = ?
(m + 2) 2 + (n - 1) 2 + (p + 6) 2 = 0, then find the value of 2m - 3n + p.
Find the value of ‘x’ in the given expression:
(49/16)x × (64/343)x-1 = 4/7
If x = (√13 + √12)/ (√13 - √12) and y = (√13 - √12)/(√13 + √12), then find the value of 4x2 – xy + 4y2.
...If x ,y,z are three integers such that x +y = 8,y +z =13 and z +x =17,then the value of x2 /yz  is:
If 9x² + y² = 37 and xy=2, x, y>0, then the value of (27x³ + y³) is:
If x + y + xy = 118, such that x < y and both 'x' and 'y' are positive integers, then find minimum value of (x + y) .
