Of the two numbers, 1/5th of the greater is equal to 1/3rd of the smaller and their sum is 16. what are the numbers? Options: 6,
10 9,7 12,4 11,5 (first option gives you right answer) – solve by observation only. www.afterschoool.tk

Wages of 8 men and 6 boys amount to Rs. 33. if 4 men earn Rs. 4.5 more than 5 boys, determine the wages of each man and boy? Options:
1.5, 3, b. 3 &1.5 c. 2.5 &2 d.
2&2.5 Try from option b. – you get the answer. Alternatively, let us assume wages of man = x, and that of boys = y. 4x-5y = 4.5; 8x +6y = 33 (multiply the first equation by 2 and divide it from II). 16Y = 24 ; Y = 1.5 and X = 3 ans. www.afterschoool.tk

The sum of the digits in a 3 digit number is 12. if the digits are reversed the number is increased by 495. reversing only ten’s and unit digits increases the number by 36. What is the number? Option:
327, 372, 237, 273 Let us try with first and III options. 72-27 = 45 and 73-37 = 36. thus 237 is the right answer. www.afterschoool.tk

Demand and supply equations for a certain commodity are 4a +7b =17 & b =a/3 +7/4. where A is quantity and B is market price. Equilibrium price and quantity will be ?
Taking LCM of 3 &4, we get: b = 4a+21 / 12 or 12B -4A = 21. subtracting it from 1st equation : 4a and 4a gets cancelled. Let us add 7b +12 B = 19 B. let us add 17 +21 = 38. we get: 19B = 38 or B = 2 Putting this value in first equation : 4A +14 = 17 A = ¾. Answer.

The age of a person is twice the sum of the ages of his 2 sons. 5 years ago his age was thrice the sum of their ages. What will be the age of person after 5 years?
Let us assume age of person is X and sum of 2 sons age is Y. X = 2Y. Or X-2Y =0 X-5 = 3 (Y-10) (because 2 sons = 2*5 =10) = X -3Y = -25 (subtract 1st equation) Y = 25 and X =50. Thus age of the person will be 55 after 5 years. Ans.

What is the value of 4+ 1/ 4+ / 4+ …. To infinity ? Let
us assume that the number is X. 4 + 1/x X is infinite series, the value of which will be close to 4.2. Thus 4 + ¼.2 = 4.2 approx. answer.

If 2^(2x+3) -3^2*2^x +1 = 0, what is X?
Options: a. 0,1, b. 1,2 c, 0,3 d 0, -3. Let us try from option: let us assume =2 2^7 -9*2^2 +1 =0; 128 -9*4 +1 = 0 ( in correct). Let us try with 1. ; 2^5 -9*2 +1 = 0 (in correct). Let us try with Zero; 2^3 – 9*1 +1 (true). Let us try with 3:; 2^9 – 9*8 +1 (in correct) Thus option D is correct answer.
