Question

Agar ek school mein Sattar percent ladka hai aur 756 ladkiyan hai to total ladkon ki sankhya kitni hai

Answer 1

Ans. boys = 1764

Step-by-step explanation:

if there are 70 % boys so, there will be 30% girls

now,30 % = 756

let total no. of students be y

then,30 % of y = 756, 30/100 x y =756

=so, y =  756 x 100/30 = 75600/30 = 7560/3 =  2520

so, y = 2520

total no. of students  = 2520

if 756 are girls then, boys = 2520-756 = 1764

therefore,there are 1764 boys in the school.
