N.B. : Question No. 4 এর Answer হবে C) 199, Not D) None of the above There is a Calculation mistake done by me. Sorry 😞 for that. Question No. 16 এর Solution : Let us assume cost of 1 apple, 1 banana and 1 Orange be Rs.x, Rs.y and Rs.z respectively. So, according to Question 4x+7y+5z = Rs.48 3x+2z = Rs.15 Adding these two equations we get - 7x+7y+7z = Rs.63 i.e., x+y+z = Rs.9 Hence the answer is B) Rs.9
Sir 24 number math tai typing kichu ta a,b er vul diyeche, lekha ache a train speed 25 km/hr, b train 20 km/hr..... Jeta apni a train 20, ar b 25 dhore korechen, ses e 8+2 =10 am
A + B= 12 B+C= 15 C+A= 20 TOTAL WORK WILL BE LCM OF 12,15,20 SO 60. EFFICIENCY OF A+B= 60/12=5, EFFICIENCY OF B+C= 60/15=4, EFFICIENCY OF C+A= 60/20= 3 TOTAL EFFICIENCY WILL BE 2(A+B+C)= 12, A+B+C= 6 FOR INDIVIDUAL EFFICIENCY PUT THE VALUE OF A+B, AND GET C EFFIENCY LIKE 5+C= 6 C= 1, PUT THE VALUE A+C AND U GET B EFFICIENCY 3+B= 6, B= 3. SO, B+C =3+1=4. B AND C TOGETHER CAN COMPLETE THE WORK 60/4= 15

Question No. 16 এর Solution :
Let us assume cost of 1 apple, 1 banana and 1 Orange be Rs.x, Rs.y and Rs.z respectively.
So, according to Question
4x+7y+5z = Rs.48
3x+2z = Rs.15
Adding these two equations we get -
7x+7y+7z = Rs.63
i.e., x+y+z = Rs.9
Hence the answer is B) Rs.9

Welcome! Keep Practicing...and following SiSan Academy...
16. 4:7:5 means 16 unit=48/-
again
3:2 means 5 unit=15/-
then 1 unit=3/-
So 1+1+1=3 unit x 3/-= 9/-
Okey, But in that case we have to consider :
Price of 1 Apple = Price of 1 Banana = Price of 1 Orange
, which was not mentioned in the question...
22.The question might be ..if B and C work individually ....then answer will be 12 ... although I am not sure about it...u can check.
Hi, just read again.
But as per given language, the answer is D) 15
A + B= 12
B+C= 15
C+A= 20
TOTAL WORK WILL BE LCM OF 12,15,20 SO 60. EFFICIENCY OF A+B= 60/12=5, EFFICIENCY OF B+C= 60/15=4, EFFICIENCY OF C+A= 60/20= 3
TOTAL EFFICIENCY WILL BE 2(A+B+C)= 12, A+B+C= 6
FOR INDIVIDUAL EFFICIENCY PUT THE VALUE OF A+B, AND GET C EFFIENCY LIKE 5+C= 6
C= 1, PUT THE VALUE A+C AND U GET B EFFICIENCY 3+B= 6, B= 3. SO, B+C =3+1=4. B AND C TOGETHER CAN COMPLETE THE WORK 60/4= 15
আমার কথা রাখার জন্য ধন্যবাদ boss...❤❤❤
