> If 4apples and 6oranges cost 13/ and 2apples & 4oranges cost 7/ find cost of one apple and one orange. Sol: subtract 2nd eqn from 1st then we have 2a2o=6 =>1apple and 1orange cost 3/
> If a person travels for P km in t hrs and then increases his speed by x km/hr find his new speed. a) (p/t)+x b) pt+x c)p/x+t d)pt/x ans:a
> A man has to dilute milk from 36lts which costs x/ to y/ a litre wat is da amt of water that he should add ?
> If avg. of 6 nos. is 8 and later 2 new nos. are added such that the avg of the present 8 nos is 6 then what is the avg of newly added two nos. Sol: avg=total sum of values/ no of objects or observation ? 8 =total sum of values of 6 nos /6 ? total sum of values of 6 nos=6*8=48 now when 2 new nos are added applying same formula 6= total sum of values of 8 nos/8 ? total sum of values of 8 nos=48 so the value has not changed which means the sum of added 2 nos is zero so avg=zero/2=zero
> If you divide a number by 5 and 7 then the reminder is 2 If you divide that number by 35 then what is the reminder ?
> The Arthematic mean of .... .. .. ... (i dnt remember )

> By what % should a person sell an article so as to gain a profit of 24% even after giving a discount of 10 % Sol) the easiest way to solve such problems is by assuming the cost price as 100rs So to get a profit of 24% means to sell at 100+24=124/ So suppose he sold it at 10% discount initially he sells at 90rs so ther is a difference of 34/ (options were a)40% b)45% c)50% d)60/ )
> Matrix addition: If 1 2 3 1 1 1 0 1 2 5 7 9 = 3 4 7 + 2 3 2 2 3 4 1 1 1 1 2 ? then what is the value of ? (some thing like this )

> A red light glows every 10sec, yellow every 15sec and red every 18sec. find the number of times all three glow together from 8:00AM to 9:00AM (including both times) Sol : LCM of 10,15,18 = 90 So every 90 seconds all three glow together so in one hour there are 3600 secs So 3600/90=40 times but answer is 41 because they glow at 0th second that is at 8 Am since both times are included.
> The bus was traveling at a distance of 60 mts before a car in 20 secs da car is ahead of bus by 40 mts if the car was traveling at a rate of 30km/hr Find the speed of da bus ? ans : 20m/s

> If a kite is at a height of 75mts from ground and the angle of inclination from a point on ground is 60degree then find length of the kite sting. Sol: based on trigonometry heights and distances: sin60=height of kite/length of string(altitude/hypotenuse)
>sqrt625.13 * 16 + 1667.66 / 17 == ???? ( dont remember the values correctly)
> 135.55 * 565 = 76 % * x Find x ? ( values r nt da same )
