Ok mam 🙏

[@cleweric]

All these logical and aptitude related questions reflect the importance 6th to 8th standard mathematics

[@amiteshydv5999]

Thank you so much Ma'am ❤ For this placement aptitude series .... Please ma'am complete this series 🙏

You make the calculations complex it can be simplified like in the last question 190 and 133 the 19 is common so we can simplify the equation beforehand to ease the solving of question

[@dollarpedia]

Thank you mam please continues 🙏

[@sakshambj12030]

question 4 is like the gear system numerical

[@dollarpedia]

First question trick 💥 Given Area so X and Y will be same value X=Y= 150 Formula 👇 X+Y+XY/100 150+150+150×150/100 = 525% Ans Mza aaya to like krna❤

Ma'am there is a question in which area of a rectangle is 221 cm2. if breadth increases by 2 cm and length decreases by 2 cm, it becomes the square. what is the perimeter of original rectangle is? This was a question asked in mock test of Accenture. Plz explain it ma,am.........PLZ

[@eeshaanmj8656]

where did u get mock test for accenture. Can u provide me also.

consider one of the sides as a and the other side as a+4 ( since they have said that it willl become a square if you increase one by 2 and decrease the other by 2). now you get a quadratic -> a(a+4) = 221. Solve this to get the sides as 13,17

[@MissPandey]

IT WILL BE 60, AS (l-2)=(b+2) [sides of square are equal] than equate the value in l*b=221 , u will get a quadratic equation of b(square)+4b-221=0 , after solving u will get 13 and 17 , Now perimeter = 2(13+17)[ formula:2*(l+b)] , u will get 60.

[@sujaljain254]

in first question percentage increase should be 625% mam

[@3lpme]

Area increased was the qsn? So its how much area more than the previous area

[@sinchanaravikumar7983]

10:05 why do we minus a^2??

[@ShubhamKumar-km8pm]

Thanku mam

[@rahulphatak2909]

Practice questions are too hard. Can you pls provide solution?
