Question

Mukuls weight is 15%of ankits weight and 18 % of alis weight what percent of alis weight is equal to ankits weight? Options: 160 140 150 120​

Answer 1

let the weight of ankits be a and alis be b

so,

$mukuls \: weight = \frac{a}{100} \times 15$

and also,

$mukuls \: weight = \frac{b}{100} \times 18$

equation both equ.,we got

$\frac{a}{100} \times 15 = \frac{b}{100} \times 18$

$15a = 18b$

now let b be 100 so,

$15a = 18 \times 100$

$a = \frac{18 \times 100}{15}$

$a = 120$

so,

the per. of alis weight is equal to ankit is,

$= \frac{120}{100} \times 100$

$= 120\%$

so option (d) is correct
