1.7654325 എന്ന സംഖ്യയെ 11 കൊണ്ട് ഭരിക്കുമ്പോൾ ലഭിക്കുന്ന ശിഷ്ടം എത്രയാണ്?

Explanation(5)

ഒരു സംഖ്യയിൽ നിന്നും 3/8 കുറച്ചു വീണ്ടും 1/8 കുറക്കുമ്പോൾ 5/12. ആദ്യത്തെ സംഖ്യ ഏത്?A) 11/12B) 3/8C) 13/24           D) 11/24Explanation:Let 'x' be the first number. Then,x − 3/8  − 1/8 = 5 /12x − 4/8 = 5/12x − 1/2 = 5/12x = 5/12 + 1/2x = 5/12 + 6/12x = 11/12Solution∴  The first number is 11/12.4.1 . 25
0 . 25 / 1 . 25 + 0 . 75 =A) 1B) 0.5C) 0.75            D) 0.25Explanation:Given, 1.25 −0.25 ÷ 1.25+ 0.75By BODMAS rule,1.25 − 0.2 + 0.75=1.05 + 0.75=1.8If the expression is given as(1.25 −0.25) ÷ (1.25+ 0.75), then byBODMAS rule,brackets comes first, without brackets division comes first.So, (1.25 - 0.25) / (1.25 + 0.75) becomes= (1.00) / (2.00)=   0.5Solution∴ Answer given is incorrect, correct answer is 1.85
Let CP be the Cost Price of the saree, it is stated that he got 20% profit, then Selling Price is 120% of CP120%  of CP = 1380(120/100) × CP = 1380CP = (1380 × 100) / 120CP = 1150Solution∴  The actual cost price of the saree is Rs. 1150.9.+8 × +12 ÷ +4 ×
6 =A) 144B)– 144C) 4            D) – 4Explanation:+8 × +12 ÷ +4 × –6By BODMAS rule,+96 ÷ +4 × –6+24 × –6–144Solution∴   The answer is Option B) –144.10.160m നീളമുള്ള ഒരു ട്രെയിൻ 200m നീളമുള്ള ഒരു പ്ലാറ്റ്ഫോമിൽ നിൽക്കുന്ന ഒരാളെ 8sec കൊണ്ട് മറികടക്കുന്നു. പ്ലാറ്റ്ഫോം കടന്നു പോകുന്നതിനു ട്രെയിനെടുത്ത സമയം എത്ര?A) 20 sec.B) 18 sec.C) 40 sec.           D)8 sec
വിട്ടു പോയത് കണ്ടുപിടിക്കുക.9, 11, 15, ______ , 29, 39A) 19B) 20C) 17D) 21Explanation:9,       11,     15, ______ ,  29,    39↓↓                            ↓11
215– 439– 10= 9= 11= 29Let's assume difference between 15 and the next no. is 6. (from the above pattern: 2,4,...,10)∴ x– 6 =15∴ x= 21
Let's verify x is indeed 21, so we assume difference between 29 and the x is 8. (from the above pattern)∴ x = 29
8 = 21 ( that also gives 21 as the answer)
Given,x = 4y                 ---------------- Ix*
4 = 7(y – 4)    ---------------- IISubstituting I in II,4y – 4 =  7(y – 4)4y – 4 = 7y –283y = 24y = 8x = 4y = 4 × 8 = 32Solution∴   Abu's current age is 32
