1.Of 90 students 76 had atleast one course in physics.86 had both How many had only chemistry? (It was solved using venn diagram)

2.One jar A contains half of wine Another jar B which is double in size of A contains 1/4 th of wine Both r flled with water and pour into another jar.Whats the ratio of water and wine in third jar (get the ratio in equal masses ans : 1/4wine 3/4)

3.I had some money, i gave half +1 to one begger, then rnaining half +2 to another , then another half +3 to another begger .Now i have one rp left.How much money i had at first? (ans 42 (1,4+3,10+2,21+1, total 42))

4.Speed of a goods train and passenger train (question in shakundala devi Ans Twice)

5.There are six men.A,B,C,D,E,F Some conditions given find out the men as whoz victim, whoz judge , whoz police officer, whoz witness (try to solve problems like these in grorge summers) 6&7.Three groups(Two question where like this) 1.says truth 2.Says lie 3.says both three statments given for each identify the group of each

8.There was a rlation like a+b=1100 b+c=1300 c+d=3300 d+e=600 e+f=1700 f+a=2300 Find the values of each. 9.age of a and b have sane digits but reversed.c's age is half of the difference between a and b.B's age is 10 time that of c's.Find ages of each (ans a=54,b=45,c=4.5)

(It was solved using venn diagram)

2.One jar A contains half of wine Another jar B which is double in size of A contains 1/4 th of wine

Both r flled with water and pour into another jar.Whats the ratio of water and wine in third jar

4.Speed of a goods train and passenger train (question in shakundala devi Ans Twice)

5.There are six men.A,B,C,D,E,F Some conditions given find out the men as whoz victim, whoz judge , whoz police officer, whoz witness (try to solve problems like these in grorge summers) 6&7.Three groups(Two question where like this)

1.says truth

2.Says lie

3.says both

three statments given for each identify the group of each

8.There was a rlation like

a+b=1100

b+c=1300

c+d=3300

d+e=600

e+f=1700

f+a=2300

Find the values of each.

9.age of a and b have sane digits but reversed.c's age is half of the difference between a and b.B's age is 10 time that of c's.Find ages of each (ans a=54,b=45,c=4.5)
