Question three. The Straight Line 2x + 3y = 12 Passes Through:

Answer :

The normal way to resolve those type of questions is to put x = 0 once and locate y coordinate. This could constitute the point wherein the road cuts the Y axis.

Similarly put y = 0 as soon as and locate x coordinate. This would represent the factor wherein the line cuts the X axis. Then be part of these points and you may get the graph of the road.

So while we positioned x = zero we get y = 4.

When we put y = 0 we get x = 6.

So when we be a part of those factors we see that we get a line in 1st quadrant, which whilst extended each facets would go to 4th and 2d quadrants.

Question 4. In Δabc, ∠a + ∠b = 65°, ∠b + ∠c = 140°, Then Find ∠b.

Question 6. 2 Workers, One Old And One Young, Live Together And Work At The Same Office. The Old Man Takes 30 Mins Whereas The Young Man Takes Only 20 Mins To Reach The Office. When Will The Young Man Catch Up The Old Man, If The Old Man Starts At 10.00am And The Young Man Starts At 10.05am?

Answer :

Let the rate of old guy be: x m/min and that of younger man be: y m/min

If the distance of the workplace be D meter, then A/c: D = 30x = 20y or y = 1.5x

Let younger guy catches old guy after ‘t’ mins.

So distance travelled via younger guy is ‘t’min = ty = 1.5tx

And distance travelled by using old man in ‘t+5’min = (t+5) x = tx + 5x

Therefore, A/c: 1.5tx = tx + 5x or zero.5tx = 5x or t = 10min

So younger guy catches the old man at 10:05 AM + 10min i.E 10:15 min

Alternate technique

Old man takes 30 min i.E. He travels from 10:00 AM to ten:30 AM

Young guy takes 20 min i.E. He travels from 10:05 AM to 10:25 AM

From symmetry; they will meet in mid-way of the journey at 10:15 AM.

Question 25. Sum Of Three-digit Number Is 17. Sum Of Squared Of Digits Of The Given Num Is 109. If We Subtract 495 From That Num We Will Get A Number Written In Square Order. Find The Num?

Answer :

Let the nos be: abc

As sum of the digit is 17. Therefore, a+b+c=17----(1)

Also sum of square of digits is 109 i.E a^2+b^2+c^2=109----(2)

Also, (100a+10b+c) – 495 = (100c+10b+a)

or, (100a – a) + (10b – 10b) + (c – 100c) = 495

or, 99 (a-c) =495 or (a - c) = 495

The feasible combos are (6,1) (7,2) (eight,3), (nine,4)

For 1st aggregate (6,1); b = (17 – 6 - 1) = 10 which is not viable

For second combination (7,2); b = (17 – 7 - 2) = eight but a^2+b^2+c^2 =! 109 so now not possible

For 3rd mixture (8,3) ; b = (17 – eight - three) = 6 also a^2+b^2+c^2 = 109 so it's miles feasible
