hi

this is Rk

for finding Qs like this we have answer

ok

there is a zoo. after counting their heads we got 90.those are dogs and peacooks.their legs are 224.

how many dogs are there?

to answer these type of questions you hava to do

first think 45,45.

count there are 270 legs(4*45+2*45)

now difference is(270-224)=46;

the incrementing value is 2(4-2)

now 46/2=23;

so dogs are 45-23=22;(22*4=88)

peacooks are45+23=68(68*2=136)

dogs 22

peacooks 68
