Demo starts here:
1. Circle Values:
Explanation: This question is asked in CPO Paper 1 Oct 2023. You that when radius is 7, Perimeter is 44. In question, the perimeter is 13.2 is 3 times 4.4 , Perimeter is 3 times, so the radius will also be 3 times. So 3 times of 7 is 21 and the answer is 2.1
2. Multiple of 11:
Explanation: This is also asked in CPO 2023. Volume is asked. and volume should be a multiple of 11 (from the basic forumula). Now check which option is a multiple of 11. It comes out to be 264 (4+2-6 =0). So 264 is the answer.
3. Multiple of 9:
Explanation: The option should be a multiple of 9 as the option should be completely divisible by 9. So 900 is the answer.
4. Digital Sum or DS: Jaha answer accurate pucha h waha Digital Sum Lagega. You can use this trick in Compound interest questions of any exam.
Explanation: Example: 12345 Sum of 1+2+3+4+5 = 15 and 1+5 is 6.
1247 * 8563 = digit sum (1247 ) + digit sum ( 8563 )= 5*4 = 20 = 2+0 = 2
5. Approximation: Is trick ko mostly division p use karo. Ise tab use karna jab options door door ho.
Explanation: 1234567/17 ~ 1234570/15
In the above example, Jaise mene kia h waise hi karna. Approximate to the nearest no for easy calculation.
5. Value Putting: When you have some variables like x, y, z.
Explanation: This is SSC CPO 2023 latest question.
Put e=0 , theta = 45 degree. Put 45 degree in Cosec + Cot^3.Sec
you will get 2^3/2. In options put e=0 and you will easily get option 2 as answer.
