• ## Question: AD is a line segment B and C are points in the interior, such that AC=BD. How ca...

Posted in: Mathematics | Date: 05/10/2017

From the above figure we get that AC = AB + BC BD = BC + CD It is given that AC = BD Plug the value of AC we get AB + BC = BC + CD … (1) According to Euclid’s axiom,when equals are subtracted from equals, the remainders are also equal. Subtracting BC from both side in equation (1), we get AB + BC − BC = BC + CD − BC AB = CD Hence proved

• ## Question: The perimeter of a triangular field is 450 m and its sides are in the ratio 13:1...

Posted in: Mathematics | Date: 05/10/2017

We can see that the ratio can be used to find the factor So perimeter of triangle =a+b+c This gives 12x+13x+5x=450 Thus x= 450/30 X= 15 So A=12 ×15=180 B=5×15=75 C=13×15=195 We know that 12:5:13 is a Pythagorean triplet. Hence the triangle here is a right angle triangle with base 5x and height 12x or vice versa and hypotenuse is 13x Thus we can use Area= 1/2(base *height) Area = 1/2(180*75) = 6750 m²

• ## Question: Mr. A has x children with his first wife and Ms. B has (x + 1) ch...

Posted in: Mathematics | Date: 07/10/2017

Mr.A has x children while Mrs.B has (x+1) children. After they got married, totally they have 10 children. But it is not given how many children do they have after they got married. Let they be 'y'. Then, we get, x+(x+1)+y=10 i.e. 2x+y=9. Here, if y can take only odd values, otherwise, x will not be a positive integer for any even value of y. Then there are following cases: 1) for y=1, x=4 and x+1=5, 2) for y=3, x=3 and x+1=4 3) for y=5, x=2 and x+1=3 4) for y=7, x=1 and x+1=2 5) for y=9, x=0 and x+1=1. As the children of same parents cannot quarrel, only y can quarrel with x and (x+1) and x can quarrel with (x+1). Then from above five cases, we have to consider the case which will give maximum value. It is the the 2nd case. That is, the product xy+y(x+1)+x(x+1) will be maximum for y=3, x=3 and (x+1)=4, that is 33. Hence 33 is the answer.

• ## Question: In a circle, XP and XQ are two tangents to the circle with centre O, drawn from ...

Posted in: Mathematics | Date: 24/10/2017

join OP, OQ and OX

using RHS we can show triangle POX and QOX are congruents and hence XP=XQ.

so basically if X is an external point and XP and XQ be two tangents from X to a circle then XP=XQ.

using the same logic for external point A we can show AP=AR as AP and AR are tangents o the circle from external point A

and similarly for external point B we have BR=BQ

so XA+AR= XA+AP = XP

and XB+BR= XB+BQ= XQ

XP=XQ (FROM ABOVE)

so XA+AR= XP= XQ = XB+BR

• ## Question: What should come in place of the question mark (?) in the following number serie...

Posted in: Mathematics | Date: 16/01/2018

The given number series is based on the following pattern :

• 1548/516=3
• 516/129=4
• 129/43= 3
• 43/10.75=4

Hence , 10.75 will replace the question mark

• ## Question: How do you descale a Philips steam generator iron?

Posted in: Physics | Date: 16/01/2018

• Tilt the base, remove the EASY DE-CALC knob and pour in 500ml of water
• Tighten the knob back in place, switch on your steam generator and wait 5 minutes
• Press and hold the steam trigger whilst ironing a piece of cloth
• Continue until water tank is empty and scale particles have flushed out
• Empty the water from the Easy De-Calc when your iron is cool Perform the deep clean once a month to prolong your steam generator's lifetime!

Posted in: Physics | Date: 16/01/2018

When you mix magnesium with hydrochloric acid, the hydrochloric acid dissolves the magnesium and produces Hydrogen gas. The less concentrated the hydrochloric acid is, the slower the magnesium dissolves. If the hydrochloric acid is mixed with the magnesium, then it will result in a chemical change
