It integrates railway expertise with IT, data analytics, and AI for intelligent, scalable training systems. Sanraksha features smart learning, feedback, and real-time monitoring.
?% of 500 = 674 - 18% of 800
If (7a + b) : (7a - b) = 7:3, then find the value of a:b?
120% of 400 + ?% of 520 = 1000
√ 225 x 24 - √ 144 x 18 = ?
85% of 620 + ? % of 1082 = 4855
√11025 x √5625 - (50)² = (?) + (73)²
What will come in the place of question mark (?) in the given expression?
737 + 149 - ?²- 367 = 14 X 25
Find the value of ‘x’ if (5 × 196 – 340 ÷ 17) ÷ 20 = √1600 – x.
