## 6 ways to expand knowledge apart from reading books

Apply your knowledge. Knowing is never enough. More you apply better you get. Make notes from books. Revise like exams. One reading is never enough. Every time I reread any book, I get a new insight. We pick only those things which are necessary for our immediate survival. As life progresses our challenges change and hence we need better insight. Activity and traveling are always helpful in getting more practical knowledge. Writing your thoughts out always helps. Introspectio

## ABCD*4=DCBA. What are the values of A,B, C and D?

I will try to solve this problem in least number of complex mathematical steps possible. I will not use any maths greater than grade 8. ABCD*4 = DCBA implies A must be less than 3 since A is at 1000s place and 3*4 = 12, which makes the given number a five digit number. Thus A can be 1 or 2. Since DCBA is a multiple of 4 it implies that A must be even and hence A is 2. A is 2 again implies D must be 8 or 9. (D cannot be less than 8 since it is at the 1000s place of DCBA, which

## What is the interval of a for which the equation ||x-2|+a|=4 can have four distinct solutions for x?

There are two solutions or no solutions. If we take ‘a’ as positive then two solutions are for a < 4. Similarly two solutions when ‘a’ < -4. There are two ways to solve the problem. Refer images for the same. Long Answer Short answer Last line says : Similar results when a < -4.

## What is the remainder when the digit 111,111 up to 124 terms is divided by 271?

The basic concept employed in this solution is that 100,000 divided by 271 leaves remainder as 1. Hence all the terms having powers greater than 5 or multiples of 5 are giving only remainder as 1 multiplied by corresponding coefficients. For example remainder when 10^11 is divided by 271 = 1*10 = 10, since 10^10 will give remainder as 1 only. This simplifies the problem. Refer attached image for full solution. #Maths #Remainder #basicarithematic

## Fresh fruits contain 80% water, and dry fruits contain 15% water. How much dry fruits can be obtaine

Fresh fruit = Real Dry fruit (No water) + Water Dry Fruit = Real Dry Fruit + Water Hence 1 KG of Fresh Fruit = 200 grams of real dry fruit ( We counted water content of both fruit + Dry fruit). Now 1000 grams of dry fruit has 15% water i.e. 150 grams of water. Hence 1000 grams dry fruit has 850 grams of real dry fruit. Thus 100 grams of real dry fruit is obtained from = (1000/850)*100 = 117.64 grams of dry fruit. Hence dry fruit obtained = 68*0.2*1.1764 = 15.999 KG End Note :
