  1. Correct Option: B 5358 x 51 = 5358 x (50 +1 ) 5358 x 50 + 5358 x 1 =267900 + 5358 = 273258

    Correct Option: B

    5358 x 51 = 5358 x (50 +1 )
    5358 x 50 + 5358 x 1
    =267900 + 5358 = 273258

  1. Explanation Time gained in 6 hours =360/30= 12. 3 mins increase in 30 mins so in 6 hrs will increase by 12x3=36 min. So need to add 6 hrs 36 mins to 5 am. So the time will be 11: 36 am.

  1. Explanation Suppose the man travels 2 miles from A and ends at D by taking turns at  point B and C. If we draw the fig and try to extend the line AB where a parallel to CB is drawn from point P and crosses the extended line of AB at E. So if we see the fig ADE triangle will form a right angle triangRead more

    Explanation

    Suppose the man travels 2 miles from A and ends at D by taking turns at  point B and C. If we draw the fig and try to extend the line AB where a parallel to CB is drawn from point P and crosses the extended line of AB at E. So if we see the fig ADE triangle will form a right angle triangle.  AD is asked. AD= root over of DE square+ AE square. DE=CB, AE=AB+CD. So DE=4, AE=2+1=3. AD=√(16+9)=√25=5 miles
