m < P = measure of the angle P = angle P

Given    2 * angle P = 3 * angle Q, and angle C = 100⁰.. To find the measure of angle B

The two triangles ABC and PQR are similar or corresponding.. So
    angle A = angle P
    angle B = angle Q
    angle C = angle R
   angle A+ Angle B + angle C = angle P + angle Q + angle R = 180°

angle R = angle C = 100°

angle P + angle Q = 180 - angle C = 80°
angle P + 2/3 * angle P = 80°
   => angle P = 48°
   => angle Q = 32° => angle B = angle Q = 32°
