उत्तर : 4. "100/7%"
व्याख्या :
Answer: D) 100/7% Explanation: When profit is calculated on Marked Price (M.P) then, C.P = M.P - P% Let M.P = 100 => C.P = 100 - 30 = 70 But S.P = Rs. 80 as he gave 20% discount, Now, Actual Profit = 80-7070x100 = 100/7 %

प्र: In a plane 8 points are colliner out of 12 points, then the number of triangles we get with those 12 points is 1324 0

उत्तर : 3. "164"
व्याख्या :
Answer: C) 164 Explanation: For a triangle, we need 3 non-collinear points. So with 12 points (when all the 12 are such that any three non-collinear is12C3. But among them 8 points are collinear. If all these 8 points are different we get 8C3 triangles as they are collinear. In 12C3 triangles, we do not get 8C3 triangles Therefore, The number of triangles we get = 12C3-8C3 = 164

प्र: A, B and C started a business where their initial capital was in the ratio of 2:3:4. At the end of 6 months, A invested an amount such that his total capital became equal to C's initial capital investment. If the annual profit of B is Rs. 3000 then what is the total profit ? 1323 0

उत्तर : 3. "Rs. 10,000"
व्याख्या :
Answer: C) Rs. 10,000 Explanation: Ratio of investments of A, B & C = 2×6+4×6 : 3×12 : 4×12 = 36 : 36 : 48 = 6 : 6 : 8 But given that the annual profit of B is Rs. 3000 => 6 ratio = 3000 Then for the total annual profit of partners is 20 ratio = 3000 x 20/6 = 10,000.

प्र: When a number is divided by 138 the remainder is 26. What will be the remainder if the same number is divided by 23 ? 1315 0

उत्तर : 3. "3"
व्याख्या :
Answer: C) 3 Explanation: Number = quotient x divisor + remainder;so, herenumber = 138 k + 26=> (23 x 6k) + (23+3)=> 23(6k+1)+3so, remainder is 3.

प्र: Manju borrows Rs.5000 for 2 years at 4% p.a. simple interest from Sudha. She immediately lends it to another person at 6 1⁄4% p.a for 2 years. Find her gain in the transaction per year. 1314 0

उत्तर : 4. "Rs. 112.5"
व्याख्या :
Answer: D) Rs. 112.5 Explanation: Manju borrows Rs. 5000 for 2 years at 4% p.a. simple interest She also lends it at 6 1⁄4% p.a for 2 years => Total Gain = 6 1/4% − 4% = 2 1/4% So her gain in the transaction for 1 year = The simple interest she gets for Rs.5000 for 1 year at 2 1⁄4% per annum = PTR100=5000×94×1100 = Rs. 112.5/ year.

प्र: An automobile financier claims to be lending money at S.I., but he includes the interest every six months for calculating the principal. If he is charging an interest of 8%, the effective rate of interest becomes ? 1313 0

उत्तर : 2. "8.16 %"
व्याख्या :
Answer: B) 8.16 % Explanation: Let the sum be Rs. 100. Then,S.I. for first 6 months = (100 x 8 x 1) / (100 x 2) = Rs. 4S.I. for last 6 months = (104 x 8 x 1) / (100 x 2) = Rs. 4.16So, amount at the end of 1 year = (100 + 4 + 4.16) = Rs. 108.16Effective rate = (108.16 - 100) = 8.16%.
