Will be posting some csat questions for practice here on a daily basis!

**@Naadan_Parinda** In my defense I was testing the image uploading algorithm, to compress images whilst uploading so that page does not slow down and the new smiley from the drop down

**@Neyawn**😊 (I was also testing the smiley) never mind. Both answers are correct.

45. A gardener increased area of his rectangular garden by increasing its length by 40% and decreasing its width by 20%. What is the area of new garden?

Apply formula for such area change questions:

(X) + (Y) + (X) (Y) / 100

Here X = +40% Y= -20% so change in area would be

(+40) + (-20) + (+40) (-20) /100 = 40-20-8 = +12% (Area will be INCREASED by 12% !)

😊

44. Income of A is 20% higher than that of B. Income of B is 25% less than that of C. What % less is A's income than that of C?

Change all such %age questions in p/q format , then workout with LCM method reverse engineering.

20% =1/5 , 25% = 1/4

5 and 4 ka LCM = 20 Assume this as C income

So C=20 units then B= 20×3/4=15 units

B=15 units then A= 15×6/5= 18 units

So A/C %age = (20-18)/20 ×100 = 10% !

**@Yo_Yo_Choti_Singh**These shortcuts are very less time consuming.

@Yo_Yo_Choti_SinghThese shortcuts are very less time consuming.

1. Practice makes u more perfect.

2. CSAT m time issues bhut kam hotey h if you know the basic techniques of attempting questions.

3. These are SSC shortcuts - converting in p/q form and LCM method makes calculation very easy and less error prone. 8×4=32 type calculations will cause less errors vis a vis 0.8×0.4 kind calculations under tensed environments.

4. But yes you need to practice well to get more perfection in these !

**@Yo_Yo_Choti_Singh**Thanks a lot 🙏
