In any given month, how many pregnancies should be registered with the ANM of this village?',correct:'10',options:['10','11','12','13'],exp:'Calculating expected monthly pregnancies registered with ANM: Annual births = Birth rate \u00d7 Population \/ 1000 = 25 \u00d7 5000 \/ 1000 = 125 births per year. Since a birth follows a pregnancy, expected pregnancies per year \u2248 125. Monthly pregnancies = 125 \/ 12 = 10.4 \u2248 10 per month. (Some calculations account for pregnancy wastage: total pregnancies = births + miscarriages\/stillbirths \u2248 125\/0.9 \u2248 139, giving ~11\u201312\/month. However, the standard UPSC\/CMS formula uses: Monthly registrations = Annual births \/ 12 = 125\/12 \u2248 10.) The closest standard answer is 10. Note: Some sources use the formula (Birth rate \u00d7 Population) \/ (1000 \u00d7 12) = (25 \u00d7 5000) \/ 12000 = 125000\/12000 = 10.4 \u2192 10.

In any given month, how many pregnancies should be registered with the ANM of this village?',correct:'10',options:['10','11','12','13'],exp:'Calculating expected monthly pregnancies registered with ANM: Annual births = Birth rate \u00d7 Population \/ 1000 = 25 \u00d7 5000 \/ 1000 = 125 births per year. Since a birth follows a pregnancy, expected pregnancies per year \u2248 125. Monthly pregnancies = 125 \/ 12 = 10.4 \u2248 10 per month. (Some calculations account for pregnancy wastage: total pregnancies = births + miscarriages\/stillbirths \u2248 125\/0.9 \u2248 139, giving ~11\u201312\/month. However, the standard UPSC\/CMS formula uses: Monthly registrations = Annual births \/ 12 = 125\/12 \u2248 10.) The closest standard answer is 10. Note: Some sources use the formula (Birth rate \u00d7 Population) \/ (1000 \u00d7 12) = (25 \u00d7 5000) \/ 12000 = 125000\/12000 = 10.4 \u2192 10.
